I run Niri and Dank Material Sell on Fedora. It’s perfect, and better than Omarchy from what I’ve seen. I much prefer scrolling window managers to tilers.

Yup. I've been on zirconium (https://github.com/zirconium-dev/zirconium) for a while, and it's great. Fedora atomic/bootc under the hood with Niri+DMS. Basically bombproof.
