When I create a new Space on macOS, I set the desktop background to an image associated with the task I will complete in the Space. Something like:
% set-space-background monitor=1 space=2 ~/backgrounds/streamer-workbench.png
If there is no off-the-shelf command or application, a pointer to the correct API is also fine for me as I can produce an application from it.
As an example use case: when I am going to stream I create a new desktop, set the background to a photo of a microphone, and populate the Space with my streamer applications.

- How do I change desktop background with a terminal command? - For an older version of MacOS. Not for changing an individual desktop.
- How to change desktop wallpaper for all virtual desktops? - Not for changing an individual desktop.
- Setting System Preferences via script - Not specific to my situation.
