Tailscale is a layer on top of wireguard and is a VPN. Don't open your home to the outside world, that's just asking for trouble.

Tailscale is a great choice for you at this stage for accessing your stuff from anywhere and not worrying about anyone else. Downside is if Tailscale decides to enshittify some day you (a lot of us) will have to figure what our next move is.

For the casual and/or beginner, it really is an excellent service even at the free tier.
