That's tough and ultimately your decision to consider. You say that funding is less of an issue though a 3000+ difference per year is nothing to scoff at so my first thought would be to really examine the finances of each school and how they relate to cost-of-living, moving, your jobs, etc. (also you mention 4 years, are you not being offered funding beyond those years?).
I don't think the US News ranking will matter much between 57 and 60, though if you're thinking about prestige you can always ask professors which place seems more prestigious and if they would pick one over the other because of this. That said, as someone astutely pointed out in another thread, schools have different regional prestige, so, if you know you're going to want to stay in the School B area because that's where you have family/history, perhaps School B is actually better for you.
As for the the topics, there's no inherent value in any topic, so I would go wherever you feel you could do what you're most interested that. That said, note that you might (and probably will) shift your topic around once in the program and that people might leave or might not be a good fit for you, so basing your entire decision on the topic is risky and might not pay off, even though it's an important consideration.
I'm not sure if doing all of your education in one school will negatively impact you on its own. However, what this means is that you won't have a variety of backgrounds, contacts, sources, and faculty to draw from when on the market. Going to different schools means you know a variety of people, who can offer varying perspectives and knowledge-pools that can be helpful later on. That said, there's also something to be said for forming very strong connections with fewer people, too.
All of your comments seem to suggest that School B is a better fit for you as a person (rather than, perhaps, as a scholar). When I was looking at schools, where my partner would be comfortable was a huge consideration, but it's really up to you to think which of all these (and more) considerations sway you more and what is more important.
You should look at Brandeis University. One professor you may be interested in working with is Emilie Diouf, who studies trauma and film. She is in the English department doing research on women, trauma, Anglophone/Francophone African film, critical theory, etc. The graduate student whom she currently advises studies trauma from a different cultural context. Caren Irr is also great for contemporary film here. David Sherman studies mourning and elegy. And Jerome Tharaud studies American religion and literature.
