I’d install a single gang box and let the wire dangle.

I purposely ran all my ceiling wires to boxes. Easy for the next owner to add an AP mount or throw a cover over if they don’t want to use it.

Everything runs back to patch panels in the basement (and is labeled), so all wiring conveys with the home and all hardware goes with me.

I was thinking the same.

It might be a little pricey compared to the rest? It works very well for my use case and I’ve never been bottlenecked by the VPN which is nice.
