I live in a house that has CAT 5 cable in the walls running to wall plates in various rooms.

Would it be possible to remove the existing regular switch, replace it with a powered POE switch, and then plug in a POE device into one of the wall plates?

Also, for the non-POE devices already plugged into wall plates, would they be okay?

I'm trying to wrap my head around the interoperability of POE and non-POE and struggling.

Check out MoCA adapters. You need one for each wall plate you want to convert and one for the modem side. Check out this site for a diagram and more info.
