Cable management is a skill that very few master.

I would suggest you google “cable management products” and see if you get any ideas. You can buy a few trinkets that can help you, such as ties, cases to roll spare lengths of cable (shortening them), grill shelves you can attach to furniture to rest adaptors and stuff, and also things that help to keep your cables from tangling similar to those toe nail separators.

But there is no magical solution, getting any of these may help but you still need to do the thinking and the heavy lifting. Good luck!
