IVPN perhaps?

Not being an expert it seems as though your setup is windows-centric, whereas KVM tends to shine on linux.

Or headscale.

Dozens… yt channels, tech blogs, changelogs, etc

Proton?

It’s a cosmic cabal! The aliens are coming!

Data packets through radio?

Software Defined Radio?

Check out the gemini protocol and the small web, lots of rabbit holes there.

You could use a VPN i guess.

Why swedes, why?

VPN: Headscale is an open source, self-hosted implementation of the Tailscale control server, which itself uses WireGuard under the hood.

For the file share, i’d say separate into two groups/VMs probably.
Whatever you might want to self-host publicly (are you sure?) keep it isolated. Its own VLAN, IP/host/subnet, container, VM heck its own hardware if possible. Or use a VPS and only self-host your private stuff in your LAN.

For what you should host: that’s up to you. I’ve heard jellyfin’s used a lot for media stuff.

Paid tiers only i think, but yes.

If the hat fits, that’s up to you ;)
