You're cable mad!
The absolute best piece of advice is to first consider whether a) do you need those devices plugged in all the time, and b) do they actually need to be somewhere visible/accessible. If they don't, then move them to a cupboard or buy some sort of standing unit that the device can be hidden in, and various cables can be terminated at.
You're never going to be able to eliminate wiring, your smart speaker for example has to be plugged in somewhere. So either move it somewhere closer to a plug socket, or pin the cabling to the wall. You're lucky having a white wall and white cabling that it's not going to be noticeable.
Chargers that you use in the middle of the room are always going to cause a problem. If you're going to the lengths of replacing the skirting and removing some of the flooring for laying wires then i would look at putting in (or having put in) floor sockets that can be hidden under your sofa. You said in your video you don't always like the look of them, but you've gotta weigh up which looks worse, trailing cables from the wall, or a flap on a floor socket that can hide away your cables when not in use.
