I guess its possible that something is not completing its shutdown

If you turn off rhgb and quiet on the kernel boot line,
you can (usually) watch lots of messages on the console as
it tries to shutdown and see things like:
A start job is running for shutting down some stupid service
stuck on the screen with a timer ticking away.
Example: I found dhcpd won't stop in fedora 31 without a huge
timeout:
https://bugzilla.redhat.com/show_bug.cgi?id=1768604
(supposedly fixed, but not yet in updates).
Sorry for the long delay to a reply as it was blocked b/c of size for
moderation. Here it is minus the screenshot of the hang.
I removed the wireless card in case something with dual-pathing with the
wired connection was the problem, and reinstalled from scratch from new
media again, in case there was a problem with the new F31 install. This
install has no extras other than restoring home from backup, installing
the updates and installation and configuration of Thunderbird. It does
the same thing, so I'm pretty sure that this is not a faulty
installation problem.
Turning off rhgb and quiet at boot results in the unquiet shutdown, but
no more enlightenment. The screen output looks ok.
Doing a "systemctl poweroff" causes the same hang as the normal poweroff
from CLI or from GUI.
I have not yet tried the suggestion to relabel the whole filesystem.
Since this is a fresh install, I would assume that would be unnecessary.
The suggestion to hit the escape key does not work in this case. When
the system hangs, I have no keyboard or usable screen to debug with, as
the system is almost all shutdown.
I also forced an fsck per one of the suggestions, to no effect. It
still hangs.
I'm starting to suspect a broken ACPI change in the newer kernel, but
I'm stuck...
