It sounds a bit silly, but I have been there a lot. For me there was thoughts left over from an unfinished day that would keep me up. It took me years to figure out what the underlying issue was. Insomnia sucks.
Honestly, I don't think it makes a huge difference for desktop users. I use Nobara because it has built in comparatively out of the box. I also run Fedora 42. All work pretty well.
I'll PM you.
