Inter Display - all UI stuff, it is designed for max legibility on screens. In Debian repos as fonts-inter

PragmataPro - all monospace/code. Paid for it 15 years ago and worth it, best mono font

Utopia Std - all serif document text. Purchased all the way back in 1998 and used for every doc i’ve ever written.

Props also to the complete IBM Plex family which is solid for sans, serif, and mono versions.
