My workshops were a total mixed bag; the quality is so dependent on the instructor and the cohort. Overall I've been pleased with it. There are a few instructors who I avoid because they have a bad reputation (either for being vicious or only open to hard realism), and there are a few people in my cohort who I try not to end up in workshop at the same time with (for similar reasons). You can't tell what the atmosphere's like until you get there, so if you do get in a few places try to visit, or ask for the email of a current student. For a genre writer, you might think about avoiding programs which are known to be overly competitive, because that can put people in survival mode and make them a bit cliquey and non-inclusive. On the other side of the coin, be wary of the all-inclusive, we-take-all-types-but-offer-no-funding schools like Columbia, because while you can find a workshop that exactly fits your needs, it's almost never worth the price tag.
In my experience, the impulse to write the "workshop story" (which is code for a dull but well-written, very literary, very realistic story in which nothing much happens, but which the workshop can't find fault in) is self-imposed. The first few times you or someone else brings something risky to workshop and it doesn't work can make you retreat back into the safety zone. But the first time you bring something risky to workshop and it does work, that's where you can really start sinking into your voice. (Another note, it doesn't sound like this is an issue for you but I think a lot of people don't get into an MFA program the first time around because they're sticking to safe workshop-y stories, which means they're interchangeable with all the other safe, workshop-y stories in the pile.)

Can I ask which authors are stylistically similar to you? I might have a few school ideas.
Here's an essay from Saunders about his experience at grad school, and how for a time he lost the spark in favor of being over-literary: https://www.newyorker.com/books/page-turner/my-writing-education-a-timeline
