Tumbler is the thumbnailer for Thunar, from XFCE.
Where does it store its thumbnails? Where is the thumbnail cache?
I managed to see
#define THUMBNAILER_CACHE_PATH "/org/freedesktop/thumbnails/Cache1"in the source code for Tumbler. Not sure if it's useful. I can't find the rest of the path, nor can I find this portion on my machine.
It's not ~/.thumbnails, and it's not ~/.cache/thumbnails. I know this because thumbnails newly generated are not added to those locations.

$XDG_CACHE_HOME/thumbnails. XDG_CACHE_HOME defaults to ~/.cache.

I can see that you should be right, but it's definitely not the case. I just deleted both those directories and the thumbnails are still generated already. Also, there is no XDG_CACHE_HOME set in my shell.
I do think thunar is using tumbler because it wasn't creating thumbnails so I installed tumbler per googled instructions and now it does generate thumbnails.

Do you maybe have another thumbnailing service running?
What happens if you run tumblerd manually:
pkill -9 tumblerd; /usr/lib/tumbler-1/tumblerd...what output is generated?
Also, if you run "pstree", does tumblerd show up as a child to the systemd process?

Now revisiting the images newly generates thumbnails, and in the predicted location of ~/.cache/thumbnails (/normal)

It sounds like there might be another thumbnailing process running on your system.
The tumblerd process will start and stop when needed. It should be running as thumbnails are being generated.
