Confusing free as in freedom with gratis there

I’d start with internal services first before opening yourself up to the outside, starting with Jellyfin possibly. Docker is worth learning as it’s agnostic to the system you are using and helps with prototyping/testing quickly - something invaluable as you learn and make mistakes in your journey. From maintaining the fun stuff, such as your media service, you’ll learn the other stuff, like ssh keys, Reverse proxy &c: Iterative improvement is the game when it comes to your homelab and yourself.

For as long as there are other distros to use, it will always be opt-in; shame, I liked Fedora.

Puzzle/mystery VNs that are my favourite: 9 Hours 9 Persons 9 doors; Virtue’s Last Reward; AI Somnium files.

I went about the same route with DT880 pros and then a FIIO BTR5. I can then use my BTR5 with my Moondrop Arias IEMs or in my cars.

If file access was the only issue with Flatpak, I would try also installing Flatseal as it will allow you to change the access of each application. I tried Snaps on my Mum’s Ubuntu machine (I run Fedora, for reference) and I hated it spamming lsblk like it were docker swarm.
