Federated self hosting - Lemmy Cafe

Is there a good way to self host a federated service at home without port forwarding? Is it possible to use cloudflare tunnels or tailscale funnel and still connect to the federation?

Slightly unrelated: is having your own instance and then federarating, just like people do with Mastodon, also equally valuable with Lemmy?
I'm not sure what exactly you mean by valuable
