First and foremost, you do not have to apply ED anywhere. If you don’t have a clear first choice, don’t apply ED at all.
Regarding the schools you’re interested in…
BC does have that combination of a smaller school, but still with school spirit and sports fandom. It certainly isn’t the only school that fits those criteria, though.
If you think Tufts is too quirky and not “rah-rah” enough, I can’t imagine you liking CMU any better.
Are you in-state or out-of-state for UVA?
What criteria got you down to these four schools? All fine choices, but I can’t quite infer what they have in common, as opposed to all of the other possible choices.
Could you graduate from all of these schools debt-free? Med school is expensive.
“Psychology and premed” is a fine plan, but it narrows down your options very little. Literally hundreds of colleges have reputable psychology programs and could give you solid preparation for med school.
All of these schools except UVA offer ED2. Maybe you should wait. Work on your applications. As you write those “Why our school?” essays, reflect on, indeed, why? If a clear favorite emerges, switch that application to ED2. If not, that’s fine.
