I think you have a great chance at UF, and a slight chance at the reach schools. Definitely worth applying if you have the time for essays and the application $.
The reach schools are likely to be swayed by how you write and describe the impact of your ECs more than being impressed by them. Why did you do them, what did you learn, and what next?
Finally, your math grades and highest level of math are going to be important too. Most top business schools like to see Calc BC at a minimum.
