Also, I see versions of metadata_db_prefs_backup.json. Might I be able to use that as well? Would that get all of most of my settings back?

Then, I'll figure out a safer way to manage things. And, once I figure this out, I can keep my books on the cloud, it's "just" the Calibre files that should be local? Is that correct?

Thanks for any help with this!
You'll need to figure out which of those files are the ones you need, and after restoring them you'll need to run Check Library, especially the part about the database and files matching.

And the book files need to be local as well, not only the database files.
