Those and ds-lite are good. Ds-lite is clearly more deployed and mature on
many fronts.

Please take cgn off the table if possible.

At this point i will suggest that you also consider rfc6877. It is better
than ipv4 only cgn since major traffic source (netflix, fb, google,
youtube....) are already ipv6 end to end.

t-mobile us has deployed rfc6877 to over 25 million subscribers.  It is
baked and works well for mobile, but you asked for residential. Rfc6877
also covers the fixed line case too.

Anyhow, the solution that is best for your network is the one that proves
itself best in your own testing and proof of concept. This will show
deal-breakers and vapor ware

Proof of concepts and friendly trials with real customers are much more
insightful than anything you will learn on this list.

I would avoid 6rd unless you have and L1 or L2 limitation that prevents
native ipv6.

I would avoid ipv4 only cgn entirely since the roi will be so poor, it is a
move backwards and you will have to do the real ipv6 project again in a few
years.

That's why I was trying to find commercially deployed cases based on either
