I like to have a tidy desktop.
That way, when I work on something and fiddle around with windows, info and downloads etc., I can shuffle stuff around, until I'm done, and clear it all away. Like a physical desktop. And of course I have Dock and Finder bar on auto-hide.
I've a folder with 150+ astronomical images that I've collected over the years (Hubble, J. Webb), that rotates - a new random image each day. They really look beautiful on my new 55" LG OLED TV. With a screen resolution of 1600x900, I can navigate it from almost anywhere in my livingroom. I have three sets of bluetooth keyboard/mouse around the room.
Also, I have a little app called Quitter, that quits or hides apps after a set period of inactivity - so after using an app in full screen on a different space, when I come back to the desktop, it's usually as tidy as this. Any mail, messages windows etc that I've used are hidden. It's how I like it.
