Cloudflare lets you create tunnels for free which will keep your site online when the IP changes. This will also hide your IP as your DNS entry will be pointed to Cloudflare.
Giving a second shout out to pangolin. You can also manage a multi site set up quite easily with built in auth and without much command line foo. Super useful if you run something like proxmox and eany go spin up several services without too much configuration on each service to expose to the world. Really happy with pangolin.
