Well here's the verdict so far on code editor themes.

Nord is actually the color palette I like the most, but unforunately the way it's implemented lacks enough contrast for my eyes to be able to use it. I'll probably use the colors for some fun projects sites coming up: https://www.nordtheme.com/docs/colors-and-palettes

Dracula / Darcula is a bit too much contrast (I know I know, goldilocks).

But Ayu Mirage feels REALLY good. https://github.com/ayu-theme/ayu-colors

Thanks for the suggestions everyone!
