I just wanted to give an update. I did, indeed, get my server physically working. However, I could not figure out how to install from the thumb drive to my hard drive. After hitting a point of personal frustration, I went with Debian 12, as the installer figured out enough about the hardware to get me up and running.
HOWEVER, I will say that all of my testing and prototyping on Armbian systems was still of great value, and Armbian will continue to be the workhorse on my (way too many) single board computers, especially my collection of wayward Orange Pi systems.
Thank you for your response, Igor. I absolutely respect the time you put into this and my hat is off to the entire team.
