I'm still having good luck with Sonoma, but I was clearing out some games and other bits to make space. Finder reported after things had been deleted that there was less free space. I restarted a few times with no success, but after running WhatSize software to determine what was so large, I had almost double the free space, from 151 GB to 298 GB free.
Hopefully, they'll improve this in the future.
