I would strongly suggest getting at least 1 physical cable to the
room, to handle the wifi router in the room.
You will need a power socket for the wifi router also.
Also, if you are running 1 cable, run 2 at the same time (the cost is
the installation, and not the cable cost really), in case one fails
over time, you can just use the other.
Also, there are some legal requirements around phones, so you might
need a phone in the room and patching phones through the network
cabling is easy.
I think the legal requirement is that in case of emergency, there must
be a working phone nearby to call 999.

I find running the cables under the floorboards, or above the ceiling
tiles is the easiest.

If you can get the ethernet cable, and power to above the ceiling
tile, you can hide the router above the ceiling tile and you won't
know it is there.

The ceiling tile option is quite good, because it hides everything
away in the ceiling, and you don't have to dig out wall sockets.
Just make sure it has ventilation, so it does not get too hot and
cause a fire risk.

I have designed wifi for entire warehouses and there it is far more
complex, with things like noisy machines and metal structures
interfering with wifi.

Kind Regards
