I'm a big fan of cheap (as in ~$10/yr vps) and reverse proxy over wireguard. My home ip isn't exposed and I'm able to quickly spin new containers up by updating my reverse proxy config and adding a wireguard peer.
I keep two VPSs- one as reverse proxy for all my miscellaneous services and another solely for email. The latter port forwards raw traffic over wireguard to my email server container. That way, even if the VPS gets compromised, my personal data remains secure.
I end up paying ~ $30/yr (+ whatever I'm paying in electricity) for domain + VPS. It's a bit more involved than tailscale, etc, but I'm willing to put in a little extra work to make sure I'm not at the mercy of some company getting up to some rent-seeking bullshit.

The full price is like $24/yr, so even if it goes up, meh.
