So for something like Jellyfin that you are sharing to multiple people you would suggest a VPS running a reverse proxy instead of using DDNS and port forwarding to expose your home IP?

I run my Jellyfin on Tailscale and don't expose it directly to the internet. This limits remote access to my own devices, or the devices of those I'm willing to help install and configure tailscale on. I don't really trust Jellyfin on the public internet though. It's both a bit buggy, which doesn't bode well for security posture... and also a misconfiguration that exposes your content could generate a lot of copyright liability even if it's all legitimately licensed since you're not allowed to redistribute it.

But if you do want it publicly accessible there isn't a hoge difference between a VPS proxying and a dynamic DNS setup. I have a VPS and like it, but there's nothing I do with it that couldn't be done with Cloudflare tunnel or dyndns.

What VPS would you recommend? I would prefer to self host, but if that is too large of a security concern I think there is a real argument for a VPS.

I use linode, or what used to be linode before it was acquired by Akamai. Vultr and Digitalocean are probably what I'd look to if I got dissatisfied. There's a lot of good options available. I don't see a VPS proxy as a security improvement over Cloudflare tunnel or dyndns though. Tailscale is the security improvement that matters to me, by removing public internet access to a service entirely, while lettinge continue to use it from my devices.
