The best, secure and easy way to access a home server, that runs on a private/dynamic IP is to use Tailscale or Holesail to access it from outside of your LAN.
Another option is to run a VPS somewhere cheap and make a Wireguard VPN tunnel to your home router. That way not only you can access your server through the VPS IP/domain but you can also have your own private VPN for external devices and browse ALL your home devices like it would be in LAN (and totally private).
