I had a similar issue to yours when I manually ran this update on my 16". It froze on a black screen, after doing the BridgeOS part of the update. I had to force it down. When it started, it continued the update and, thankfully, everything worked.
However, I'm still having kernel panics after the Supplemental update. But interestingly, they only happen when the machine is supposedly sleeping, with the shell closed. I kid you not. I will have it sitting there on my end table in the living room, shut for over an hour, and all of the sudden it will reboot with the lid closed (I know because I have the startup chime enabled). I've never had a Mac kernel panic while supposedly sleeping. This is so f*cked.
Bugs me too. Your best bet is launchd which solves the problem, but it is a bit of pain to write job definition property lists. More here:

Ironically -- I think this bug is fixed in a like 10.15.3 or so. Eitherway a cron I set up over a year ago before I realized this bug has started mailing me since I updated to Catalina.
Ah, thanks. That jogged my memory. I did turn off power nap a long time ago, but my laptop still kept waking up at night anyhow. But I just checked, and now it seems to work as advertised.

I appreciate the transparency here. Outside of API documentation, a lot of plain-language information doesn't go in-depth enough about MDM capabilities.
Yes, I know this, but when a Mac does this, it does it only to run routine Apple code, stuff that should not, under any circumstances, cause a kernel panic. And up until Catalina, that it never has, barring binary corruption or defective hardware.
In this case, the kernel panic seems to be related to the Intel Iris video driver.
