Chris, if you don't care about local granular control you can check out the
free tier from ControlD (Windscribe's DNS company). They allow you select a blocklist (the Hagezi range, OISD, 1Hosts etc) and use their DNS with that blocklist for free. Hagezi Pro or Pro Plus include a large subsection of TIF already, meaning you'd get a decent, off the shelf ads+TIF coverage with good response time. Their CDN is fairly decent (I get 2ms to them), and they have DoH/DoT/DoQ available. Alternatively, you can select multiple of their own curated lists (eg ads, malware and phishing) and use those at the same time in a single endpoint, free of charge. Worth considering if that's all that matters to you.
ETA: I have a lot of time for Quad9/PCH, they're good people. I know a couple of the netops/engineers and they care a lot about fast DNS and online safety.
