Thanks! I ended up getting a bundle with a bunch of different monospace fonts (https://2bitcrook.itch.io/44-game-boy-fonts) and experimenting with which one looked best, and then we agreed on Everybit Original.
Fonts can be a pain in Godot if you're working with Pixel Art. The important stuff:
1. You have to change the Font Import settings per font to remove things like Anti-Aliasing and Sub-Pixeling. It is not enough to change your project settings unfortunately.
2. Only resize them to multiples of its native size (in this case 8, 16, 24, etc).
If you (or anyone reading) plans on using pixel fonts in Godot, I hope that this can help save some headache in the future. :)
