@alium I've tried installing "accountsservice", but no luck, autologin still doesn't occur.
Here's the latest log from "current" (after several reboots in disbelief):

@linuxer I've checked out the Arch thread, but it was about being unable to login as he kept getting the password wrong caused by an unexpected keyboard layout. Did I miss something there?
Additionally, the time you're referring to is after +7s, which should be after I've inputted my password.
@Dudemanguy Just a speculation, but I believe that I was forced to input my password without autologin between these times:
2021-02-13 15:45:39.608070294 [+4.79s] DEBUG: Prompt greeter with 1 message(s)
2021-02-13 15:45:42.584706105 [+7.77s] DEBUG: Continue authentication
So, the time at [+7.82s] that you're referring to should be Xfce starting after I've already inputted my password.
Just to be super duper sure about the timings, I've rebooted, then left LightDM waiting for my password input:
