I'm a fan of the Red Hat font family, i.e. Red Hat Display, Red Hat Text, and Red Hat Mono. They are available via CDNs, font providers, and directly from Red Hat:
To be fair, the person could still use Google Fonts, but just download the font and host it themselves. The font licenses allow this.
You get the upsides of being able to pick a nice font from Google Fonts while not having the downside of tracking. It also helps with caching! And also prevents the font from disappearing for no reason.
Not on Google Fonts but it's free (or very cheap for the variable version).
