Type of cable to use

I need to run cable under a covered porch (not underground), can I use Romex-NM or is UF required? The floor is approx. 2 feet off the ground,

NM-B can only be used in "normally dry" environments. That is of course up to the interpretation of your local inspector. If there is doubt about it, I would lean toward using UF-B and outdoor-rated boxes. Unless it is a fully enclosed room it will likely get very wet from wind-blown rain on a regular basis.
