Real homes have cable ducts -- I'm limited to drilling through walls.
Unfortunately, due to lousy electric installation I'm stuck with

I would have put in a heavy ground wire strung along the CAT 6/7).
Galvanic separation would be a god-send -- but for the price

bear in mind that ordinary ethernet both coax and twisted pair is galvanically isolated.
