I run one of these free cloud vms as a reverse proxy for my reverse proxy. It runs rathole, which my homelab rathole client connects to, and it patches traffic through ports 80/443 into my homelab to my caddy container. My home ip is never made public and I don't have to forward any ports at home or worry about traversing NAT. It's a neat setup, but rathole hasn't been updated in some time and I'm looking to replace it with an actively developed alternative like gost or connet.
