If you can go up in to an attic or down to a basement or crawl spapce directly above or below that floor, that would be the easiest.

If not, drill the walls, put in metal or plastic conduit or other allowable raceway where it is minimally obtrusive to the room ifpossible. Pull bulk calble throught the conduits make sure conduits or other raceway will accomodate all the wiring you need, along with bend radiuses. Look for 40% +/- fill after the cabling is in.

All Ubuntu Server at home. Been running it for many years, got tired of compiling applications on my previous distributions.
