I'm partial to Drafting Mono - https://indestructibletype.com/Drafting/ - for paragraph display.

Not on Google Fonts but it's free (or very cheap for the variable version).

Its SIL licensed. Free and open source.

IBM Plex Mono is pretty good, with a reasonable license. It's on Google Fonts, and the repo is here: https://github.com/IBM/plex

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:

Aside, but please consider using https://fontsource.org/ instead of Google Fonts: just as easy to use, and no tracking (at least from Google).

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.
