One suggestion, don’t know if this is applicable to you, but apologies if not.
I wished that I had run tubing, conduit, to make the run of future cables smooth. If at all possible I would put some sort of small piping or conduit in place, but it might make no sense in a particular situation.
If you can do so, run string though so you can pull additional cables through.
Consider running the best cable - highly over-specced - in case you need to upgrade one day. Of course this doesn’t matter if you can replace the cable easily.
Consider running additional cables through, for extra capacity future-proofing, and because it’s more hassle having to pull additional cables through later.
Don’t kink the cables, vital. (Especially with overall-foil-shield type posh cable as the foil will snap.) bending the cable to too small a radius will damage the noise resistance of the cable causing subtle errors data loss unreliability and slowness if you’re lucky, and it may or may not recover if you unbend. Don’t even bend cable temporarily.
Just a few thoughts. Things that I haven’t done as often as I should have.
