I’m not sure of the floor plan or roof type. But what I do is run a cable up the corner and drill a tiny hole right in the corner through the ceiling. Then I use a PoE powered access point and leave it in the ceiling space centrally located. One tiny hole you can patch with just about anything when you move house. If you have a rj45 crimper then the hole can be the diameter of the cable.

I’ve also done something similar where I run Ethernet under the floor. I lift up the carpet slightly right in the corner and drill a hole through the floor and run the Ethernet under the house. You also then take it up into a closet etc.

If you’re more adventurous and confident with electrical work you can also TURN OFF MAINS, then open up a wall power socket, disconnect the wires, tie a pull wire and your Ethernet cable very securely, and go into the roof and pull the two through into the roof space. You then tie the end of the elec cable to your pull wire and pull it back down to the socket. You can then get a wall plate that is a power socket and Ethernet female combo and voila….

I’ve used GlazeWM a bit before switching fully https://github.com/glazerdesktop/GlazeWM

That counts imho.

You should check out d2. It’s a code to diagram tool. You put some very simple coke and it draws your diagram. Quite quick and useful. Been using it for a while now.
