Maybe.
Things to know:
Some tomatoes make HUGE plants and that includes many cherry tomatoes. Johnny's is a good source and will say how big the plant tends to get. (indeterminate= keeps on growing and growing unless killed by cold or disease) Bigger plant= needs more water and food to stay happy.
Also- plastic pot in FLorida could suffer overheating/cooking the roots on the sunny side at least. Or- in Largo, maybe you're planting now and won't have quite the full summer effect.
In general, tomatoes can be very vigorous and productive, especially cherry types. One cherry tomato plant is all I can ever use. (keep picked)
