The only things i think look like impact craters in Florida is the entire gulf of mexico and lake Okeechobee
lake okechobee could have been formed by an impact at a 20 degree angle on where the lake currently resides, the impacting objects peices were probably burried under the limestone. and its circular shape is probably the only sign that it happened
The Gulf of Mexico could be an extreamly large impact crater which could have broken up Pangea
also notice its 'n' shape the shape could be that something huge impacted just northeast of the Yucatan.
The Chicxulub crater just southwest of the center of the possible impact basin center is just a coincidence like the Manicouagan crater is almost downwind of the clearwater craters.
Which is why the gulfs formation is a mystery because the cause is not considered to be a cosmic impact.
also the craters in the caralinas could be from a megatsunami around 2 million years ago from the east after the water receded leaving crater like structures there the anceint megatsunami could possibly be why most of the Bahaman islands have shallow water west of them.

Also there is some debate as to wheather or not Hudson bay is an impact crater or not

Where the Gulf of Mexico is right now used to be the center of a triple tectonic plate junction which is currently the present day mid atlantic ridge.
the carribean plate came from the pacific and thats why there are volcanos in the lesser antillies because the carribean plate is going against the north and south america plate the carribean plate probably came from when the Gulf of Mexico impact shockwaves created new plates in the Panthalassic ocean
which would become the current Nasca,Juan de Fuca and Carribean plates.
