Do ground cables benefit from being elevated off the floor?

I don't know. I am doing this for purely organizational purposes.

All cable connections are pathways for good and bad. The magnitude is always unique to each environment.

I’d opine if the ground wires don’t carry signal it doesn’t matter. Some people consider the - wire to be ground but it’s not, it’s signal.

I see it more as.

If you have synthetic carpet and static, the cable can be affected.

Its possible some cables could be more or less reactive to vibrations. So is the cable support a dampening device. Or is it lifting the cable off a floor that is vibrating.

Does the support reduce tension or kinks.

My PAP speakers have a crossover you can mount anywhere. When it was attached to the speaker frame of which the light metal frame rattles severly, it was easy to hear the smearing and blurr the physical vibrations imparted into the crossover. So I'm confident vibration can be a factor. Mind you, touching the frame of the speaker you notice severe vibration. Its not like putting you hand on a floor and maybe feeling something when subs are firing onto them.

Another very good reason to use elevators for cables and cords is, if you have any vibration isolators, one should ideally elevate the cables and cords to eliminate any force they might exert on the iso system. Any external forces degrade the isolation effectiveness considerable. The top must be free to move easily and without contraint.

This is very true with my STST Motus II TT. It has a sprung suspension and a hanging cable will drag on it.
To your overall point, cables dragging off anything can affect the vibration of the equipment itself. I generally see this more with cables on a rack that are hanging. I don't usually see cables on floors putting undo tension on gear. One member has his amps on Herzan stands so his cables are elevated to maintain a very neutral attachment so as to not unduly affect the way the stand reduces vibration.

You can connect an oszilloscope to a metal baking tray suspended above the floor.
Next lower the tray towards the floor.
You will measure and see an increase of noise in the scope.

Some chap here tried that to prove that raising cables from the floor does have a measurable impact.
Not only in mechanical ways.

I would be surprised if this would not affect ground cables.
