What you really want is a system with a variable speed compressor. With a variable speed compressor, your system could run continuously, mostly at a low speed and ramping up when necessary. This approach will mostly eliminate cycling and reduce wear on the system, and help maintain temperature and humidity. Unfortunately, The Villages doesn't go this route but you can when the original system needs replacing. We had a two speed Carrier Infinity system (50% and 100% compressor speed plus variable speed air handler) in a previous house and it worked great. We currently have a Mitsubishi mini-split for the lanai and it can ramp anywhere from 25 to 100% of the nominal capacity. Works great.

But many other site and talking with contractors, you want a smaller unit to get rid of the humidity.
No problem maintaining a 20 degree difference.
