You should be fine as long as you have started to get clinical volunteering hours now. On your AMCAS you should put down future hours as long as you are sure you will be doing and then you can send updates to the schools you applied to about your volunteering, and what insights it has given you.
There is no reason every single FL school should not be on your list this includes: FSU, UCF, FIU, UM, USF, UF, FAU, and the newer one Nova.
Chances are slim to none at Texas schools without being a resident or have strong ties to the state.
You have a good chance at the other schools you've listed. It might be good to throw in some more reaches if you have the funds. I believe Yale has a good public health emphasis might be worth throwing them an app. Hopkins also has a good public health emphasis.
It would be good to get some advice from the adcoms
