The only North American spider species of concern are the black widow (Latrodectus mactans) and brown recluse (Loxosceles reclusa). Unfortunately, these both occur in south Florida - but so do many other spiders.
I'm guessing the spider that bit you wasn't one of these two, for the following reasons:
If you were bitten by anything else, the odds are incredibly high that the worst you'll deal with is a little red bump of irritation that goes away shortly.
