At the end of the day how much money do you have to spend on this? A couple hundred then your choice is Caseta. A couple thousand then send me a PM and I can pull together a quote.
The Caseta switch you listed will work with the Caseta PRO bridge and Hubitat.
The Maestro switch you listed is a "DUMB" dimmer and isn't controllable. You will need to contact a dealer/installer for RadioRa 2 stuff.
