Unmotivated because my college fate has probably already been decided

What? You can gain acceptance to the vast majority of schools in this country. Only the very most selective schools , by definition, will be a challenge. Now, paying for them is a whole other story. The schools you mention do not give merit money, so those accepted get financial aid based on their definition of need. I suggest you run NPCs on the schools and see what you would be expected to pay, and have a discussion with your parents about what they are will and able to pay for your college.

Getting a full ride,like you say you can get from UF would indeed be a challenge. But odds for that, a very long shot, if the most selective schools are what your want and you need full scholarships.
