I don't actually pay for this, because the free tier is good enough for my personal needs, but Tailscale is amazing and has totally changed my relationship with self-hosting and web services.
I know that you can roll your own VPN WAN using wireguard or whatever, but honestly Tailscale makes it pretty foolproof, and that's allowed me to access all of my self-hosted stuff from anywhere with minimal screwing around. The first time I logged into my Jellyfin and Finamp from outside the house, I was pretty much hooked. If I could easily and safely host public game servers for my wider group of friends I would be even more into it and would definitely pay for a higher tier.
Linux, fediverse, signal, matrix, self-hosting services like Jellyfin and Gittea, minimizing subscription services as much as possible, embrace physical media and retro gaming, touch grass, etc.
You would be amazed how much free and open technology you personally have access to, even on modest used hardware running out of your home.
