U001 is my main system font as a clone of Univers. Monospace is Berkeley Mono—it might be paid/proprietary but boy does it look nice & was an upgrade from several years with Iosevka. JuliaMono is its fallback though since I use Unicode with frequency & Berkeley doesn’t cover all the symbols I use.

The important part is if you care anything about your fonts, you won’t destroy them by patching in that uncurated hodgepodge called “Nerd Fonts” clobbering used symbols or the wrought-with-false-positive “coding ligatures” which is not how ligatures are supposed to be used but programmers refuse to demand Unicode support in their languages to fix the problem.
