One interesting observation about IPv6 I've made is that in Europe IPv6 and FTTx seem inversely correlated. For example Spain is one of the leaders in FTTx with 87% of homes covered, but have only 3% IPv6 adoption according to Google. Meanwhile Germany has one of the highest IPv6 adoptions in Europe, 52%, and one of the lowest FTTx coverages (16%). Latvia, Lithuania, Belarus, and Iceland all have 90% FTTx and 10% IPv6. UK, Finland, Belgium, and Netherlands on the other hand seem to be having better IPv6 adoption than FTTx.

My guess is that ISPs must have needed to choose if to invest to core network or to last mile, and that is visible here. But at the same time it seems bit weird that you'd in 2020s deploy fancy new fiber networks without IPv6.

I wouldn't count it like that. Germany's top provider Deutsche Telekom has a market share of around 40% and has enabled IPv6. Vodafone as well.

Well there's no real value connecting to an IPv6 island. The Internet is still IPv4.
