At home I really appreciate the NAT. I'm glad not every device has a public IP and gets hammered with attacks 24/7. It's not fail-safe but it definitely adds some security..

As for cloud, no idea what the benefit should be there.

This is what a firewall is for.

Most people use ISP provided routers at home, firewalls in those aren't necessarily great.

It would be literally the EXACT SAME firewall with IPv6 as with IPv4 NAT.

Most IPv6 routers are also IPv4 routers and behave exactly the same for both. They share the same router code, the same firewall, etc...
