Are we past peak IPv4?

The only practical reason you'd want to use ipv6 at home is if you want to expose multiple devices on your LAN to incoming TCP/UDP connections from the Internet without doing port mapping, since your ISP likely gives you a whole ipv6 block instead of just one address like with v4.

The real practical reason, everything else aside, is that you’ll need IPv6 connectivity to reach IPv6 services as the world continues to adopt and transition over to IPv6.

So far I haven't encountered any ipv6-only services. It may happen some day, then again there might be some bridge to v4 anyway.

CGNAT is also a thing lately..

Right, some home ISPs that don't give a public v4 might give you a public v6 without a firewall. Cellular ISPs will probably have CGNAT even on ipv6, for example my AT&T is like that.
