Up through the ceiling or down through the floor. Alternatively, surface mount on a tacking strip or hidden in molding. Surface mount and molding hidden is good for a couple cables but not for whole trunks. If you’ve got trunk-like wire bundles you’re stuck with the better of ceiling or under the floor (where is there enough space to run the cables you need? You’re still going to have to drill through brick if going under the floor (or be really mindful of wire length). Ceilings usually have a means of going OVER the brick walls but you may not like the drop wires in the rooms you want a wired connection. It’d be a GREAT start for access points though…
