Just a quick note, I'm running cat6a - there's 9 runs to every room. The actual size of the cables is much bigger than non-shielded so there was hardly sufficient space in the walls.
I hope that is a 2 story house... Those runs are a nightmare to chase in the future.
Already have that covered - all linings are plywood so simply unscrew to access cables.
