You’re asking on Lemmy, so you’re going to get a lot of privacy related answers. For usability, Cloudflare tunnels are a super easy and free way to setup and don’t involve your family members having to VPN into your network with Tailscale or Wireguard. This is especially useful if they are streaming from a smart TV or media stick.
Is it the most privacy-friendly? No. You’re giving up a little bit of that for convenience and lower maintenance. IMO for my threat model, it’s worth it.
