Fedora is like it or not one of the most influential and important Distros out there.
Fedora is and will always be cutting edge. They early adopt projects and technologies that absolutely become the standard.
No other distro has this much influence. SystemD, Pipe wire, and other such projects are the norm because Fedora pushed it.
And like it or not, Fedora will make this move very soon with Wayland. Wayland is our inevitable future, like it or not.
I don’t see Arch, Debian, and others pushing things like this, but rather falling in line with Fedora.
OpenSuse has a very well defined pipeline:
Tumbleweed -> Leap (maybe Slowroll) -> SLE.
OpenSuse is not going to break new ground. It’s all about OBS and testing software before it hits their Paid Enterprise offerings. And they have almost a fully automated procedure for this. OpenSuse is not going to push Wayland only nor what will become the standard. It’s not in their ethos. OpenSuse is there to build SLE’s next release.
Debian being cutting edge?! Never. Debian is Debian, very slow to adopt anything. Debian is about offering a very stable release schedule. Debian will never push the ecosystem forward, it’s not Debian’s goal. You want a reliable system that just works? Debian is inarguably the king.
