I'm in Germany, and running my custom opnsense router with adblocker DNS connected to one of the big DoH providers. Never had any issues, not even with using plain old DNS in port 53.
Vodafone Kable, so YMMV.
Always a bit scared to switch providers of course, you never know if you get cgnat and blocked DNS servers. They are building a Deutsche Telekom fiber to our street this summer. It's tempting for the 200 Mbps uplink, But I have no idea is it then CGNAT and do they even provide real IPv6. It's never mentioned in the advertisement.
Telekom DSL and fibre should normally be full IPv4 + v6 dual stack – they're the former state operator and have a relatively generous IPv4 address allocation.
