Usually 1.1.1.1/1.0.0.1 unless I’m trying to do something specific.
1.1.1.3 for home Wi-Fi (filtering a lot of bad stuff for family members), 8.8.8.8 for devices I personally use.
Moved from OpenDNS to Cloudflare to now, NextDNS: https://nextdns.io.
I use AdGuard to block ads + tracking and it routes DNS queries through Quad9: https://www.quad9.net/
Thanks for the all the answers 🙏 I assume most people who know about DNS options are using alternatives to their ISP default, and if you don’t know the options and are using the default you probably didn’t understand my question anyway 😏 I’ll now be going down the rabbit hole of DNS options 🙌
