E.g.,

• https://github.com/URWTypeFoundry/Core_35
• https://fossies.org/linux/misc/old/ghost/AFPL/GhostPCL/urwfonts-8.71.tar.gz
• https://github.com/adobe-fonts/source-serif-pro
• https://github.com/adobe-fonts/source-code-pro
• https://github.com/adobe-fonts/source-sans-pro
• https://github.com/IBM/plex
• https://github.com/mozilla/Fira

Possibly for the UI (same designer as Lucida Sans)?

• https://go.googlesource.com/image/+/master/font/gofont/ttfs/

Possibly also

• https://github.com/impallari/Libre-Bodoni
• https://github.com/probonopd/font-newg8
• https://github.com/probonopd/font-u001
• https://github.com/probonopd/font-leutkirch

Need to look at

• https://github.com/itfoundry/hind (should have a version with rectangular iöäü)

Check

• https://github.com/Homebrew/homebrew-cask-fonts/tree/master/Casks

Are there curated lists of high-quality fonts?

https://github.com/quoteunquoteapps/CourierPrimeCode/tree/master/ttf for the terminal maybe? (It's Courier, but bolder.)
