I’m a fan of “Tom Thumb” for small OLED displays. https://robey.lag.net/2010/01/23/tiny-monospace-font.html

I wrote a kinda goofy Ada library for it https://github.com/JeremyGrosser/tiny_text

Yep, and very easy to read on low resolution. Master Of Orion have 3x5 fonts and they are very clear and easy to read.

PICO-8 code editor uses one I think.
