I’ve got a trans kid going into senior year of high school. We’ve toured a number of schools, some on your list and a few others. So no direct experience actually living on campus yet… this is based on tours, etc. Of your list we toured Vassar, Wesleyan, and Rochester. Wesleyan fell off her list for other reasons but I think it’s very trans-friendly. The other 2 are staying on the list for now. She also liked NYU and Tufts in the NE area although I’ve since heard from a mom of a gender nonbinary kid that NYU was problematic as far as bathrooms go (not very many all-gender bathrooms on that campus). BTW that friend goes to University of Oregon which has a gender equity floor in their dorms and all-gender bathrooms all over campus if you want to look further west.
Also on my kid’s list are a few more schools outside of your geographic range - Carleton, Macalester, Reed, St Olaf*, UC Santa Cruz as a local option. St Olaf might be the most problematic as far as housing goes… they are very open and inclusive and all that BUT up until now still have their housing segregated by floor (all men’s floors and all women’s floors, only). They would be fine with a trans man living on the men’s floor and vice versa but you might still feel awkward depending on where you are in your transition. But in my daughter’s interview on campus she brought the issue up and the admissions person said they’ve been getting more and more questions about having a gender equity floor or a nonbinary floor or something along those lines and it’s likely to happen ‘soon’.
Anyway, good luck on finding the right fit.
