I lived in FL for about 25 years and my family just sold their last two houses there. Depending on where you live, the insurance can range from not too bad to insanely expensive. Wind and storm insurance has made living on the coast pretty rough. If you don't need a separate wind and storm policy or can self insure, it's not bad.
I loved living there and embrace being a true Florida man, but it's lost almost everything that made it a great place to live outside of a few areas in the panhandle and big bend.
As far as taxes go, though, I don't think you can beat living there. No income tax, sales tax is comparable to most other areas, and property tax is within the norm. You kind of get what you pay for though, especially in central, west, and south Florida where it has become so overcrowded it's insane and infrastructure, schools, and services just haven't grown to meet the demand.
