This is a route I'm looking at expanding on again, I was originally getting the house cabled, but with COVID-19 that's delayed.
Any particular vendors / models to consider, I've used delvo in the past.
I'm currently meshing UI APs etc.
Mikrotik Powerline Plus. The fastest, and they pass 24V PoE for UAP-AC-Lites, UAP-AC-LR and UAP-AC-Mesh.
