FSU’s stats are 3.8-4.4 for the middle range. It means the BOTTOM 25% students admitted to FSU had a 3.8 WGPA. The middle range test scores are 27-30, meaning that a quarter had more than 30 on their ACT and only a quarter had less than 27. The bottom individual score is 580 so your SAT score would place you in the bottom of possible admits… which would make it a reach even if you had a 4.0… which you don’t. Hence, a high reach.
Where do you want to work? If in Florida or in the South, pick a FL college. If in the Northeast, look there too but don’t discount the FL system.
St Michael’s is actually pretty good and similarly ranked as UVermont. Your college GPA and demonstrated interest may indeed make you an interesting prospect to them, hard to know.
Worrying about a college being “well-known” is pointless. You yourself admitted your mother had never heard of Pomona or Haverford or other top schools, so unless you mean “whose football/basketball team is known in Florida”, you don’t need to restrict your choices with this criterion. To be blunt, show your mother the USNWR rankings and prove to her that UVermont is a Top 100 college, and the schools you got into also are, and may even be higher ranked.
Look for colleges that will admit a student with a 2.7 GPA and 1640 SAT (those are your stats, right? Or did I read that wrong?), slightly offset by a strong college GPA, AND will provide him with scholarship.
I second Flagler.
Some FL colleges may consider you a freshman with college credit (ie., not a transfer), so you could take the January SAT and present that score, thus improving your prospects. LOOK INTO IT NOW.
You could look NOW for colleges that take Spring transfers. Most state universities do. This way, you could apply in September for Spring 2017, and have two semesters’ worth of college grades (+, if you’re savvy, 2 courses taken at FL community colleges that can transfer to UVT, hence saving money - but in order to do that you’ll need to check with your adviser).
There are no federal scholarships that you don’t already have. In fact, you have pretty much maxed out federal grants and loans (which typically go to students whose families make much less than your family, so you can understand why we’re wondering what exactly your family filed for FAFSA. Please check it out.)
Your sister may get scholarships if she’s a top student in STEM, but she should plan on taking summer courses alongside doing summer research in order to make her 5th “year” into a semester.
ETA: I see that you mother won’t let you apply to FIU or other universities where you have a shot of admission. So, you’re really stuck.
Except… if she’d rather have you attend college outside of Florida so that she can keep some self image or for boasting to her friends, you need to find a cheap OOS college that you can “boost” in words so that she can boast about it. Would she have geographical restrictions too?(ie., you said she wouldn’t accept Mizzou, because it’s Missouri.)

UVermont ranks 37, ex-aequo with quite a few universities, and FSU is basically at the same level. Look at the 20 universities before UVermont and the 10 that follow, then the top 5 regional universities above. All are big public universities.
Also, at most LACs, being a boy actually gives you a boost, as does applying from 400+ miles (ie., awayfrom FL).
NCF stats: 3.96-4.44 WGPA, 27-32 ACT (and 29-34 on English +Reading).
