If possible, get fiber into the house. Biggest bang for your buck.
From everything to the switches (top of the line SOTM then Regen in series) I use wireworld cat 8. In my system this was a huge upgrade from everything else (including audioquest diamond, though other friends report just the opposite in their systems) I tried 3-4 years ago. The yellow one works for me but some friends report better results from the more expensive wireworld ones.
It should be mentioned that the rest of my home is connected to the switch with copper. Removing this connection for serious listening is a great pop up.
