Tampa area has a good number of jobs usually but is also a little depressed salary wise.
Jacksonville is pretty solid, but skews towards Microsoft/.NET people, but not excessively. Pay is usually really solid, and startup scene is good. Larger employers are banks, and JM Family.
Central Florida (excluding Tampa), so basically Orlando East to Volusia and Brevard Counties is pretty solid as well. More defense contractors in this area, pay is decent for the low cost of living. There are also a decent & growing amount of space based positions popping up. They use to be huge, but it died down for about 10 years but has started picking back up. Startup scene is pretty good, and growing.
East South Florida (Ft Lauderdale - Miami) is solid and growing all the time. Pay is good and again cost of living isn't crazy for being a known city. Startup is growing more and more with a few good successes in the past few years.
South West Florida - Ft Myers area, I rarely see anything advertised down in that area but there are some larger enterprise employers.
Key in Florida is you don't find a ton of tech only companies, usually it is businesses trying to solve problems not invent new tech. That said, there are a number of name brand tech companies in the Orlando and Miami area. Miami and Jacksonville are the best overall for startup environment with Orlando and Tampa respectively.
There are some other areas like Gainesville which kinda falls into the Central Florida category. The panhandle outside of Jacksonville is kinda weak except for state government from what I have seen.
