I personally would run Fedora Server for an easy out-of-the-box experience. It comes with cockpit and SELinux. Great for Podman, too.

I’d recommend Bitwarden for password security. It’s ubiquitous and secure, plus you can run your own instance.

For Plasma, I recommend trying out Plasmatube over FreeTube.

You might enjoy the flexibility of running Mopidy and using a variety of media players for it. You can run media over a local network with it and include several plugins for Internet radio, podcasts, and more.

Eventually I’d recommend trying out self-hosted options.

The enshitification continues. Happy to not have these problems anymore. No Windows, no worry.
