Few years ago I had a 3-month-vacation in New Zealand. Since then my desktop-background @work is a slideshow of my best 20 fotos of that trip. Great to keep the memories fresh! (And much better than the standard-desktop with the logo of the company ;-)
I like color, and I like the background to not be too “busy”. Black causes too much contrast with icons and other screen elements for me, and a busy background is distracting and makes it harder to pick out icons and such on my desktop. I also use switchable workspaces. Since I’m WFH there’s a couple for work and a couple for personal stuff. So one desktop rotates pictures daily, one desktop always has a picture of the building where I (normally) work, and a couple others have solid colors. Special shout out to Digital Blasphemy for two decades of cool desktops (I’m a paid member).

Many years ago, I used to deal with the "never see it because too many windows are open" problem by using (pseudo-)transparency on my terminal windows, so that I'd be able to see my desktop background "through" them. Great idea in theory, but, in practice, it just added background noise that made the text in the terms hard to read. So I stopped doing that and now I only see my desktop background for a brief moment after rebooting.
I used to have really cool backgrounds for my desktops, but they've turned over often enough that I haven't gotten around to moving on past the boring defaults. Which reminds me, I'd better start looking for a new desktop .. my plan is to stay ahead of the catastrophic failures.
At home all the systems have the Debian default artwork which is usually abstract and subtle. I don't use icons, and I full screen most programs, so I mostly don't see it most of the time anyway. At work I put up with whatever the client wants, though if I can get rid of their default and just have a solid black background then that's what I do.
Corporate logos are all good and well, but if you can't work out what the icons are then it's not much use... At one firm I worked for, the security team didn't want branding to be visible as they thought it was a risk, but marketing wanted it on everything, and so our badges and laptops all sported corporate logos....
