Like others here, I had a similar experience. I setup a simple minecraft server on a SELinux secured OS. So far, so good. I wanted to setup a systemd service to startup and shutdown the minecraft server.

After ~1 hour of work later, I came to the conclusion that I was going to disable SELinux. Another hour later, I disabled SELinux.

Much as the article mentions, there didn't seem to be much good help, especially w.r.t. learning what the incantations meant and how to use them properly outside of a narrow path. Similarly, I did not have any decent way of introspecting what was going on in there. The error messages were of the "you must google this to even have a remote chance of figuring out what it means at all."

I understand SELinux is probably designed for enterprise or organizational specialists and not for normies to touch. It just seemed a bit too extreme towards that end.
