Every thread about programming fonts is not complete without mentioning the wonderful website https://app.programmingfonts.org (no affiliation, I just find it really useful) which lists all the free programming-related fonts with live preview (for example every single font from the article, and every one mentioned so far in every comment in this thread is already there in the app) - it allows quick one-click preview with custom text on each font, and has direct links for downloading said fonts.

Every font from this thread is already there in the app so you might as well just try them all.
