The only solution I've found to rat-nesting wall warts is to eliminate as many of them as possible. Which is reasonably practical for things that can be Powered Over Ethernet, or stuff that lives in a rack where you can install a single unified power supply dispensing the requisite amounts of DC voles. I have a strong preference for computer equipment (network switches and the like) with integral power supplies and kettle lead inlets, on general neatness grounds. (The thing about a kettle lead being that it's easy to make one of a custom length.)
What it doesn't help with are the myriad chargers you need for charging random portable stuff (especially those with sill plugs and voltages) which is what appears to be the main issue here.
Whatever you do will succumb to cable management entropy in due course, so I'd go for the sort of solutions that involve convenient shelves, tactical blu-tac and velcro straps, rather than anything too involved. That said, I'm not beyond drilling holes[1] in shelves to ease the passing of cables between levels.
[1] Something like a 22mm forstner bit is your friend here. Neat holes that are just big enough for a booted RJ45 or an inline female USB-A.
