If you're only gone a month, you might be better off having the mail held for you rather than forwarded. That way you also don't risk mail arriving after you've already left Florida.
Another option might be the USPS's premium forwarding service, which is supposed to forward ALL your mail (including junk mail) once a week via Priority Mail. The downside of this is there is an initial fee, plus a weekly fee.
That said, I know from our financial institutions, statements and 1099's will not be forwarded via traditional mail forwarding. The latter looks like a change of address (albeit temporary) to the USPS system so this is likely due to security/identity theft concerns.
