To lay Cat5e or Cat6 cable, firstly you must decide where are you going to locate the incoming broadband line. From here, you will split all the individual access points to your living, your room, kitchen or even toilets per se.. Talk to the contractor see if he can lay it free for you since they are already hacking to conceal the electricity wires.. for my case it was a FOC case laying 2 cables to living and 2 to the masterbed room, all coming from the living hall upstairs where I will place my router etc. in.

fiber to home or in fact any wired broadband in MY will comes in from the tel pole...and it usually routes thru your house ceiling and into the wall inside your house...

If you intend to install Unifi or something...best is to ensure a route(can use a pvc pipe open up in the ceiling) is ready(concealed) for the fiber to get into your house somewhere upstairs ... From there...prepare a few Lan cables coming all the way down to your TV cabinet...that would look better.
