This may be Niche, but DAWs are very rare to support linux, especially this stack. I would say it might be a stretch to say the company behind Bitwig is punishing Wayland users, I am sure they don't have the personnel for it, but it is a legitimate issue that companies will most likely be 10 years late to the new modernization into Wayland.
Anyways, I was able to configure it with a specific flake configuration. I had issues with third party windows, which was more of an issue with the floating nature of Niri, since Gnome with Wayland displayed external VSTs fine.
You can find my repository here if interested. It consists of a few files, and I made it easier to use with justfiles. https://github.com/ArikRahman/Nixwig
