@old-sparky An intro is "Hi, I am sparky, a retired electrician and avid DIYer and gardener."
The above post needs to be broken down into the many posts it is and each placed in it's separate sub-forum.
It sounds like you have a lot of knowledge already, so not real sure what help you need.
Welcome to the forum.

Thank you Ron! It's easy to talk a good story but with little confidence, it's a completely different story!
Thank you for the guidance,
Best regards, Old Sparky.
@old-sparky A couple of quick thoughts. Regarding hard-wired, I think ethernet would be the logical choice. Piggy backing on the 240VAC mains is not something that is often done any more for obvious safety reasons.. It does exist and I think my eero routers even offer a repeater that uses the 120VAC we use here but they heavily recommend the WiFi 6 repeaters as they can easily punch through several inches of concrete in each wall of my apartment. In a house the wood and plaster are a breeze.
