I showed you easy ways to setup TURN server and you keep asking for alternatives.. did you try and hit any issue? then please ask the question using support template and many details, open one topic for each specific..
You write you read a lot - I also prefer to understand things before I start.. but there is no reason to switch back and forth different architectures just because the other look little better. There many installation kinds - from native, AiO, docker micro-service, snap to NextcloudPi etc and each of them covers specific niche, has advantages and drawbacks.
I would recommend to stick a technology you know best because self-hosting not only involves setup and initial configuration but also continuos operation efforts like backup which you need to adjust if you change your architecture..
I’m sorry to hear you didn’t feel welcome we definitely look for civilized discussions. but honestly if your previous questions are similar I can understand kind of “not welcoming” responses… Please don’t forget people spend their spare time here to hep others.. and you are asking open questions about multiple different complex questions which have been discussed many many many times already
