"Just docker run" is not always the answer
Look at Radarr:

It's nice that they give tipps about pitfalls, but there are more than this and a step by step tutorial would also be good.
Often times you have to google and search 10 reddit posts. Thinks like digitaloceans tutorial work best.
Nextcloud was 5 minutes (or 15 if one includes setting up ssh key in the web frontend for my account). WordPress was 3 minutes, Matomo also 5 including configuration.
I know that I am using a central service and am not self hosting. But for > 13 years this setup "just works".
I had a masquerading server at home once (back in the early 2000s) and updating, securing and just maintaining it was a hassle.
So to me the current setup is stable, mostly secure (and more secure than I could make it) and balances my needs for control and stability and ease of use quite well.
I think the single most important thing of any software is "how do i install this". Thats the first thing i search for on a github repo.
And please no outdated tutorials, that sucks so bad ... that i give up and don't use it.
