There's plenty out there that will work the AC/ heat pump side or the gas side, but none that would cover both. I'm sure I could horse something together with an additional switch, but would rather not.
I recently installed a Honeywell RTH9585 in my home, which will run either a AC/Heat pump or a central air/furnace option (see the system selection process at 6:45
). It gives you three heat stages and 2 cooling stages. There may be some special things you need to do with the wiring because each separate device has it's own 24 volt supply. It does require 24 volts and it is WIFI enabled.
