I guess I have rather overestimated what a normal amount of wired devices is based on my own sample size. That or the opposite is happening with you.
My house has a POE doorbell, several POE cameras, 2 TVs that each get a connection to their attached android TV boxes, Wife's office gets a pair of connections, ditto with mine, then you've got the APs for the wireless bits + a few servers in the rack with the networking equipment.
Mind you I know I am on the high side, but I use that as the reference point. I'd figure a normal house would have 4-5 wired connections to my 20ish.
In that situation I'd basically consider the doorbell and cameras as a separate install.
That mainly leaves the TVs, which I would just throw on the wireless but for wiring I'd still say you run it to your central switching spot that handles both copper and fiber.
