I believe the lack of Fedora LTS is maily to increase the sales of RHEL Workstation
I have been amazed by how stable Fedora manages to be. I think I had a problem maybe once every couple of releases that needed a fix, and the community is always there to help. The Fedora bug-reporting process is terrific. There's a lot of engagement with the users and a genuine desire to help.
The option to upgrade once a year makes this more palatable, to be sure.
I haven't tried Silverblue yet, but that might make the upgrades faster and less painful.
That said I may switch to Silverblue anyway at some point, because it really is amazing in many ways.
I'm not surprised, but Flatpaks install everything in the user's home directory. So if you know you're going to be using Flatpak apps, make /home bigger.
