Somehow I have managed to spend most my time in a house that has concrete and brick stopping 5G, a house with wooden walls that block RF and foil insulation under the floor which is even worse, and a workplace environment that has literal faraday cages all around.

I like UniFi in wall access points in the room I’m inside.

No. My house predates the widespread use of expanded metal mesh style of lath. Just the old wood strip lath and thick, horsehair plaster.
