Revisiting this thread since my last past was off topic… 
You’ve received good suggestions from other posters. I commend you for recognizing the benefits of keeping your undergraduate costs as low as possible since your goal is medical school. I agree you should revisit your list and remove any college not offering merit aid (keeping a couple instate options since they are in budget and great schools).
I shared my D’s merit results in a previous post to give you an idea of the tier of schools offering non-competitive merit to attract strong students. The LACs on her list would not meet your size criteria; I provided the details as an example of potential merit offers if you widen your list to include less selective schools.
Once you have safeties/targets from instate publics (tOSU, Miami) and schools that typically offer merit for your stats, then feel free to reach for more selective colleges with competitive merit. You never know unless you try. Also, remember to look for a place you will be happy for four years and be able to maintain a high GPA for med school apps.
I look forward to seeing your revised list! Good luck!
