for me Fedora Workstation installed fine, even when dual-booting (you have to “shrink” the Windows partition first) and it works great for me. The only slightly annoying thing is that many guides and how-tos use a debian based distro vs red hat/fedora based one (apt vs dnf, .deb vs .rpm)
I have Joplin with Nextcloud sync. It works fine for me! It’s got a desktop app and a mobile app with, in my opinion, pretty good UI. Markdown support, syncing between devices, etc. are all there. You don’t need to connect to the network to view notes, a local copy is saved.
