In addition to all responses, this is the first semester all faculty are fully in-person, which means we cannot meet so much on zoom because we have literally less time from commuting/walking across campus. Don't take it personally.

Second this, don't read into it. There are a million reasons why someone might remember your application, it might be because it was good, it might be because it reminded them of someone else. You don't have enough information right now to assume one thing or the other. Also improve your WS if you can, this is a crucial document. 

It depends a lot on discipline/dept culture. 
To me, the PhD was a job, so I was comfortable (jeans, shirts) but not in gym clothes. You never know when your advisor will introduce to the dean, take you to lunch with a visiting scholar, etc.

Friendly reminder from a faculty: August-September is the best time to contact POIs. 

This looks pretty academic-ly to me. Always, ALWAYS put the most relevant pieces of information first. Hence, I'd put teaching experience before service or extracurricular. "Publications & Scholarship" sounds redundant. Either "publications" or "scholarly work." 
The only portion you might to add some resume-style detail is for research experience, if this experience was not the norm or if it includes very different experiences. For instance, maybe you were an RA for a professor and that meant scanning books, maybe for another prof you went into the archive.

Ditto.
I do think that it certainly makes your research more interesting if you eventually include historians of other regions in your committee, but for application purposes, given the number of historians of medicine in North America, you should definitely apply to a place where there is one.

Allow to provide a different angle.
While your level of Russian might be enough for the program requirement, not all POIs admit based off that. The whole point of languages is that you use them for your research, either reading sources or reading scholars. So, in your CV you can add a line on "known languages" (no need to include they are self taught, if they are not in your transcript, people will add up). But in your WS you can show that you've used the language. Or in you SOP you can point at language training as part of your career development. Eg, you found sources that you are unable to read yet, but are confident that a summer program in X university will get you to the finish line. Or Eg 2, You plan to take three semesters of Russian at the institutions well-renowned Language Center. 
In other words, admissions are not a list of boxes that you check. Those boxes are a starting point, but you need to show how you will grow as a scholar in that specific program.

In the humanities, where research plays the most important part of your degree, coursework is that moment to build your fields. This is the moment to read things you won't read in the years doing research and writing the dissertation because your focus will be very narrow. Coursework reminds you of the big picture as you dive into your research and as you come out of it. It reminds you of your interlocutors. 
However, PhD programs vary from program to program and courses vary enormously even within the department. So your courses should be useful to you. How can you tell if they are useful? Well, you asked about employers. That's one way of thinking about it although I have never heard of anyone asking for courses taken in a PhD for employment purposes (it may vary in your field). 
Courses at the graduate level can provide: 
Mentorship. Sometimes we take courses to work with a professor that we want to include in our committee and who might eventually write a LoR. I took courses with specialists outside my department to bolster potential letter writers for the job market.  Diversity of assignments. In my program, several courses had non-traditional assignments which really helped me down the line. Eg, a course midterm was an annotated syllabus and in addition to the final project we had to write a grant application. It was the first draft I ever wrote and helped get started. Networking. Depending where you are taking courses, you can encounter students from fields that you wouldn't have found otherwise. Interdisciplinarity helped me better hone my project for audiences outside my discipline. I've also known people that because they took specific courses, they found out about internal grants that eventually funded their dissertation writing years.  Methods. Some courses offer good exposure to methods that maybe you won't use in your project but it is worth knowing they exist. In my case, this is more methods in textual analysis.  YMMV

This doesn't necessarily mean that people will come off the waitlist. 
Programs make offers knowing there will be a yield. For instance, if they have ten spots and they anticipate a 50% yield, they will make twenty offers, which means they will have their spots filled and no one will come from the waitlist. 
(Sometimes it happens that programs get a higher yield than they anticipated too and they have to shrink the next cohort). 
Of course, YMMV. 

Yeah, I'm with @psstein - I don't see enough information to make a good judgement. How much is the difference, and is the financial difference $30k vs $35k or $15k vs $20k - the same difference matters more in different circumstances. How does cost of Living in the respective cities factor in?
(NB: as of this year, most Ivy+ schools are offering $40-45k as a stipend. Unionization works ✊)

No no no no no. You should never, EVER go into anything to please others, least of all your professors. You can talk to your program where you were admitted and ask for a deferral or simply decline. IT IS OK TO DECLINE AN OFFER. Trust me. A good professor will always be proud of you, no matter what you choose, so long it's your choice. And if anyone gets offended, well, it's their problem. 

Before you accept or decline, please consider the resources at your disposal for performing a vigorous due diligence for each of your potential options. Please way the benefits and challenges (not pros and cons) of each option.
FWIW, The way I see it, you have at least five centered around attending graduate school
defer accept with intent to push through to the doctorate with your intended fields accept with the intent to reassess after earning a masters with your intended fields accept with the intent to earn a master's degree while (covertly) developing skills for a job outside of history. You could use the outside field requirement to develop a skill in data science or project management. Just make sure that the skill isn't something with a very limited shelf life.  accept with the intent to earn a doctorate with fields that will help you get a job outside of the Ivory Tower. As an example, if your top 10 school's name starts with a Y or a H or a P or a J, and your interests are anywhere adjacent to security studies/grand strategy you could put together a path of study that leads to a job with .GOV or .MIL For options in the private sector, I recommend that viable alternatives should comparable favorably to what you'd be giving up by not going to graduate school. That is, you have an offer of "guaranteed" underemployment with health insurance and great amenities (like the library) during an interval of
intensifying great power rivalry, economic uncertainty, a pandemic that doesn't care if people think it should be classified as an endemic, political turbulence. Please also take a look at your theory that you're overthinking things. To what extent is "over thinking" a trait that that has kept you out of bad situations or a potential character flaw that has led you to walking away from opportunities for personal fulfilment and success. The latter can really become a grind if left unchecked. Or so I've heard.
Please do consider talking to your professors candidly about your ambivalence. Before initiating such a conversation, make sure that you're going to be able to speak frankly about your hopes, your fears, and your understanding of their expectations. (On this last point, I think that @AP will prove to be right. I think that your professors like you personally.)

This is a good moment to inquire about the hidden curriculum of your program. For example, you can ask about the typical time of completion, the expectations in each year (including service/TAing/RAing expectations), any new developments that the program is thinking about (maybe they will start offering a certificate or maybe the grad studies committee is changing comps format). You can also ask about library resources, digital scholarship, conferences that faculty usually attend (and might bring you with), research funds available in and outside the department, etc. 
For example, in my program, students working under a prof were more or less expected to get a major research grant. For US Americanists it was a given that they will do another language even if it wasn't required. In another program that I know, grad students often worked at the rare books library or the museum. And so on. 
There are many things that faculty won't know (and it's not their job). Eg: health insurance, visa stuff, student fees, etc. 
Congratulations!
