Sorry you're having a rough experience, I came from Arch to Fedora and found it a much easier environment to just relax into, and for me relinquishing the extreme control and maintenance Arch gave me was freeing.
That said, I never dove deep into Arch, only had to use a few AUR packages, and never built my own pkgbuilds. Fedora doesn't have a strong competitor to this, if you're used to doing these things in your system, you will find Fedora lacking. I haven't had any issue finding the software I need in Fedora repos so clearly my use case is simpler and Fedora fits me better in that regard.
I haven't had issues with install groups, but then again i don't really use them. I guess they probably aren't that great or else i'd use them more. Still, hasn't been a big issue.
Idk why you have an issue with xorg, if you want Wayland Fedora supports it out of the box and was one of the first to do so, switching to it should be easy. Wayland is still missing support for key things, for example Synergy clients just flat out don't work, so having xorg support is still valuable, at least to me.
Overall it sounds like you're missing the power of Arch. That's understandable, Arch is more flexible and arguably more powerful if you're willing to spend twice the time maintaining it. Fedora has saner defaults and is set up as a more well-rounded system out of the box, but if it's built in a way that isn't useful to you and you feel like you have to bend it to your will, Arch is probably the better option.
