You can rent a Hetzner server for ~€25 bucks (has local storage and a good Intel CPU for live transcoding streams if needed), get infinite cloud storage for ~€10 and Plex Pass for ~€5 bucks. Add in a private domain for ~€5 per year and you're done. Total cost ~€40.50 per month. Hetzner gives you infinite ingress and a few TB egress bandwidth per month. As long as you only give access to your box to family/close friends you'll never hit that cap. And all they need is a Plex account. Then you just invite them and the setup is done, zero technical finnicking for them.
