I'm behind CGNAT for my home connection :(

However, I also have native ipv6 to the home for as many devices as I want. It's easy to forget that carrier NAT is expensive for ISPs as NAT hardware needs a lot of fast RAM.

I feel like I would mind NAT less if they gave all the devices IPv6, similar to how it works on some LTE networks.

But IPv6 prefix delegation doesn't always work if you put your own router behind the ISP box...

As long as you have a public IPv6 address, just use that.
