There’s a lot more than that, but here’s a quick list compiled from filtering suspicious actors (for-profit etc…) from privacytools:

• applied-privacy.net (DoH, DoT)
• libredns.gr (DoH, DoT)
• nixnet.services (DoH, DoT)
• snopyta.org (DoH, DoT)
• uncensoreddns.org (DoH, DoT)
• blahdns.com (DoH, DoT, DoQ)

Not sure about PowerDNS and Quad9 because they appear shady from the outside but they may be options as well.
