I don't see Florida as "doing much worse" either overall or recently. I also don't know what you are talking about with "no masks." Every national business has a mask requirement. Everywhere I've been in FL there is extremely high compliance in every place that requires them and with the non-enforceable local mandates. 70% of people wear them outdoors at the Costco gas station.
Municipalities in FL can, and do, limit indoor capacity so I'm not sure where in FL you are that has apparently gone back to pre-COVID.
