Several years ago I tried and tried to build a Moodle university.
I could not because programmers were changing Moodle too fast and too much.
What was simple (at first) became EXQUISITELY COMPLICATED.
What's it like now?
Still driving trainers crazy trying to get it to work?
That would be my guess.
Back then I though the ONLY WAY to get a Moodle to work was to hire a Moodle developer + hosting company.
Let them go through the HUGE problems of working with a system that is not stable enough to work with.
Any words of encouragement?
Yawn..... and moving to Comparisons and advocacy. Have fun, kids 
I briefly looked at your posts from 2019. You definitely had some problems but most of them seemed to surround innapropriate hosting (wrong versions of stuff) and you were (trying to use) Softaculous which is nothing whatever to do with Moodle, and strongly discouraged for all the reasons you discovered. So...
You also had a *load* of help at the time 
"...I tried and tried to build a Moodle university." And precisely how were you doing this? I'm not going to review the 2019 posts, but around that time, I am fairly certain that Moodle's update release schedule was pretty much as it is now. Were you setting up the standard type Moodle or were you trying to reprogram elements to "better suit" your perceptions of what it was you needed?
Sounds like you have answered your own question and rather than attempting to assist/review/assess/consult (been there, done that), etc., maybe you should check out the following rather than host your own:
