Update, been running Fedora 44 for just over 6 weeks. Settled into Cosmic after experimenting with LXQT and Gnome. Fought with partially implemented installer in Hannah Montana Linux, then gave MX Linux with Fluxbox a spin (but found it struggling with running multiple processes). Cosmic is quite bare, but that isn't an issue in coming from LXQT. Performance is fantastic, even if it doesn't "do much" beyond run a thing.
