The last line is what went wrong. It makes me think that Qtwebengine in both Stretch and Buster are now too old, but would like to see if it's working with the newer qtwebengine in Sid.

Have you tried to open any ebooks with its builtin ebook reader? That's where the errors come in. Or did you backport the 4.0.0 version that's really 3.48?
From looking at the bug reports, it appears 4.0.0 now needs a package of python 2 bindings for at least qtwebengine 5.12. Debian has that qtwebengine upstream, but they are not building the python 2 packages any longer, as part of the python 2 purge.
So Debian won't be doing any further Calibre packaging until it goes full python 3.
Users can still install the "static" build version with the command string from their website, though.

The built-in ebook reader works OK but I did indeed backport the other version:

Good question.
I fired Calibre up in Sid with sway (experimental) on my little atom and I see the version offered by Debian is 3.48 for aforementioned python2 to 3 reasons.
I used to use the binaries for Debian from Norbert Preining via MobileRead foum. He now often does it in Debian as you can see from the change log. He has been busy with it lately. But only up to 3.48
I am just going to wait a bit before even thinking about going to version 4 Not much at the MobileRead forum yet. A higher priority for me is trying out Sigil 9.18

Best of luck. peace out.
I installed their static version 4.1 via the commands given on their website, and it's working fine. It installs and uses its own libraries that aren't in Debian. It just doesn't upgrade automatically, as far as I know.

Is there any real reason to update constantly on Linux? I only have Calibre installed on my Windows host OS, but I'm still chugging away on version 2.49, and it hasn't complained about any device I've thrown at it yet... Does the Linux version do hardware mounting or something different than the Windows version?

Your love life will be... interesting.
How did it know?
The U.S. uses the metric system too, we have tenths, hundredths and thousandths of inches
Well, they do constantly add support for newer devices, as well as add or fix news sources, if you use Calibre for that sort of thing. If you don't need the new stuff, stick with what works!
