Cheese if properly vacuum sealed will not mold, refrigerated or not. Hard cheese that is meant to be kept for long storage (a few months) will benefit greatly if waxed rather than vacuum sealed, as it will age much better in wax. Keeping the cheese at warmer temps will help with aging also. Freezing will also stop any further aging at all.
I have smoked sharp cheddar that is going on18 mths 'in vac seal and fridge.
No mold problems w/ mold.
DO NOT freeze hard cheeses. It drastically changes the texture and not in a good way.
