Honestly, I think the default fonts (monospaced and proportional) on all major platforms are pretty good these days, though IBM Plex Mono and Sans have really grown on me, to the point where I use them as my default terminal (Mono) and text editor (Mono and Sans) on Mac, Windows, and Linux. On Mac (my primary desktop), I use San Francisco ("system-ui") with a couple alt stylistic sets ("High legibility" and "One storey a") as the default browser font, overriding both browser defaults and most other common "default" faces (serif and sans) via an extensive collection of @font-face directives.
