Addressing your chances since that’s what you asked:
Miami high reach - subs could be Elon, Butler, Denver, Charleston
Florida high reach - subs - Alabama and it has McCullough Pre Med Scholars. Other large flagships - Indiana, Kansas, Colorado etc
GW reach but if full pay and demonstrated interest - you never know. Same with American. Given the urbanness of these, Charleston is a like safety. Mine chose Charleston over AU which if budget wasn’t an issue would have been #2. UT Chattanooga is another
Gtown - high reach - Loyola Maryland, Chicago, New Orleans might be good subs, DePaul
F&M - reach - Stetson, Rollins, Eckerd or if want up North Wheaton, Drew, Susquehanna.
FIU is not a safety. But a target. The test is great. The rank is fine. The GPA - ehhh
FIU is potentially the only school you get into. Are you ok going there ?
If not, you need to expand your list.
Like everyone has said - budget is first and foremost. You need one.
I’m guessing you think your long list of short term ECs will get you in - but ECs don’t make up for your academics.
So expand your list would be what I’d advise.
