I use Photoshop for art. Unfortunately, all other desktop software just isn't good, but thankfully Procreate is absolutely amazing software that I can use on my iPad (if you're reading this, devs, please port it to macOS. There are countless artists that'll pay to switch to a non-subscription based, non-Adobe piece of software that doesn't suck). But for desktop, I really have no choice but to buy into the Adobe scheme.
But yes, Creative Cloud is seriously completely fucking nuts. It's shit I do not and will not ever need or want for any reason and exists just to burn through my electric bill and contribute to climate change. Trying to find ways to disable it gives you cheeky employees who post marketing fluff about how it enables consumer whatever BS, but nobody can explain what those 8 dozen background tasks are doing or why we can't disable it.
I resorted to just deleting parts of the software package one by one. Most background tasks are gone. I made the mistake of updating one (1) time and the number of background tasks doubled. Absolute insanity. Nearly gigabytes of memory swallowed and CPU cycles wasted doing nothing. For all I know, it's nothing but crypto mining processes--and honestly, it probably is since Adobe has shown themselves to be money hungry and absolutely nobody can or will say what those processes are.
