More of an issue in Florida is the humidity. When a structure is built without air leaks the interior becomes vulnerable to humidity.

That is true, When you build a tight building in Florida it is imperative that the HVAC system is not oversized. In a old conventional building it was common practice to upsize by another ton of AC just cause it was cheap insurance.
In a tight building envelope, the HVAC system MUST be properly sized so it will run long enough to get the humidity out, it is also necessary to bring in controlled fresh air.
