I’m still at about 30 more minutes to finish restoring 1½ TB of data. This was very easy so far. I’m obviously not yet finished, but I’m feeling pretty confident.

Yeah. or go to apple. I have a mac mini m1 and a macbook so it was an easy fix. This is a factory fix though. The machines they ship out need the newer Mac OS version

From a cold boot, I get to the login screen in 11 - 12 seconds. What are you seeing?

I’m seeing about 15-20 seconds for a reboot while I’m docked w/ the lid closed and a handful of external drives. Which is awesome! It seemed to always hang on getting the monitor going. My CAPS lock light would come on if pressed, but still a black screen. Now I’m actually seeing the black screen with the silver loading Apple logo.
I’ll try and disconnect everything in a bit and just try a cold boot w/ nothing plugged in. Got me curious!
Just as a heads up, I remember when updating from 11.0 to 11.1, not only the machine bricked and needed DFU restore, but even after a clean successful wipe, right away using Migration Assistant to restore from a TM backup gave me an "incomplete / cannot complete error". I didn't put important data so I decided to not deal with it and started new, so I didn't investigate whether the backup was really broken beyond use or not. But I figured some of you need to be warned if you depended on Time Machine to carry you through the already contrived restore procedures.
I erased mine for return and it was a bit of a pain in the butt.
It's weird to me after you get out of Find my Mac and sign out of icloud that before resinstalling the OS, you need to log in with your apple id to activate the Mac.
And to me, when it says activate the mac, it makes me think that I am putting it back onto my account. Which choice of words to me. Unless that is what I am doing and I did it wrong.
It's very easy on iOS of course. You just choose reset the phone and all is good.

Is the issue widespread? I have reinstalled 2 M1 MBAs and both after reinstall with official Apple stops did not accept password after reinstalling. (1x Big Sur 11.2 and 1x Big Sur 11.4)
Only thing that helped was typing resetpassword into terminal and then erase mac in erase utility.

This thread is obsolete, for the most part. The Apple instructions have been updated. I'm surprised you're still having the issue. These are the up to date instructions: https://support.apple.com/en-us/HT212030
The good news is that apparently Apple learned from this issue, and with OS12, you will not have to reinstall the OS, you can just wipe the personal settings.

I'm guessing that is auto-corrected? I can't imagine what "stops" is supposed to be.
Only step I did differently is erase volume. I used erase not erase volume.
Yes, auto-corrected.

As a complete Mac newbie, and someone who plans to wipe then return his M1 MBP in July to make way for (fingers crossed) the 14" version, I find these accounts pretty horrifying. Methinks I'll grab the user beta version of Monterey next month and use its "EZ-wipe" feature instead of risking this nightmare. Or go the "genius" bar and say, "Here, genius, wipe THIS."
Just a heads up in macOS Monterey the "Erase all contents and settings" feature can be found here:

Volume Group. Volume can mean Macintosh HD or Data. It has to be both at the same time. You are allowed the option to erase either individually, but as far as I remember, erasing either one individually, and erasing both one at a time, any of those options lead to problems.Erase Volume is way to go.

Does this only appear on an admin account or under certain circumstances? I cannot imagine the option being this readily available, the kind of support nightmare this would bring by users mis-clicking it.
