We are MDU ISP and at our managed wifi sites we see about 50-60% of our
traffic move to IPv6 when we enable it.

I see numerous statistics from Google and similar sources that indicate the
percentage of end users who are IPv6 native.   What I'm missing are
statistics going the other way - what percentage of sites (or endpoints
that customers regularly connect to) are IPv6-native, from a total traffic
perspective?

That is, if I switch to IPv6 on my eyeball network, how much of my existing
traffic will I have to CGNAT in some way to reach the IPv4-only network?

We have sufficient IPv4 address resources to stick with IPv4 for the
foreseeable future.  However, at some point, the percentage of traffic
using IPv6 becomes so high that the reasons not to move become less
significant.   For example, the CGNAT box becomes significantly smaller, as
most of the traffic should flow around it on IPv6.
