i agree with all of these. for the cable clips, though, look into 3m mounting tape. i'm using this for lifx strips, other LED strips and nanoleaf aurora tiles and they definitely stay on. you actually have to ruin the tape for the thing to come off, i know because i had to reposition the Z strip behind our 65" once and it was a bitch to peel off. no damage to the strip or TV though.

It never leaves a residue, sticks almost permanently to itself, and can hold quite well to even porous surfaces.
