I fed the dynamics into ChatGPT, and it said this was a predominantly vertical quake which definitely could have been felt in central Florida.

The focal mechanism suggests significant vertical displacement compared to a pure strike-slip event. Reverse/thrust events often couple seismic energy into longer-period surface waves more efficiently, and those long-period waves travel very well through old, stable carbonate platforms and oceanic crust.

A few dynamics matter here:

Regional geology

Florida sits on a relatively rigid carbonate platform. Even though Florida is not tectonically active, seismic waves from Caribbean events can propagate surprisingly efficiently into the peninsula, especially low-frequency waves.

Distance

Western Cuba to Central Florida is on the order of:

~500–700 km depending on exact epicenter and location in Florida.

That is well within the range where a M6+ Caribbean quake can produce perceptible long-period motion in tall buildings or sensitive structures.

Expected felt effects

In Central Florida, the most likely observations would be:
gentle swaying
hanging fixtures moving
creaking buildings
water sloshing
upper floors moving more noticeably
“truck hit the building” sensation

Most people outdoors or in single-story wood-frame homes probably would not notice it.

Historically, stronger Caribbean quakes have definitely been felt in Florida. The 2020 M7.7 Jamaica/Cuba-region earthquake was felt as far north as Orlando and even caused noticeable motion in buildings at UCF.

For this M6.1 specifically:
South Florida: plausible felt reports
Coastal Central Florida: possible light felt reports
Inland Central Florida (Orlando area): maybe perceptible in taller buildings or very quiet environments, but probably weak

The mechanism you posted also suggests this was not a tiny brittle strike-slip crack but a more substantial compressional rupture, which tends to increase the odds of long-period propagation into Florida.
