Would love to see a way to subset fonts based on unicode range of SSG output and freeze opentype axes based on font-feature-settings defined in the CSS.
Yes, lots of cool things to do around fonts! I have in TODO to add automatic system font fallback with the right metrics in order to improve CLS automatically. Is it what you call "freeze opentype axes based on font-feature-settings" or is it something else?
I would like to do the subset font optimization. I'm just not sure how much of an improvement it's going to be. Have you done it manually before?

I was talking in context of variable fonts which come with lots of features mapped to opentype tags and axes. font-feature-settings property selects (or activates) those features. Usually this is done at few CSS selector levels. The variable fonts can be trimmed by freezing those features. I did something like this with Fira Code a few years ago. [1]

It can be quite an improvement for fonts like Inter which ship with massive number of glyphs to support different languages.[2] Doing this manually is a huge pain. Zach Leatherman created a tool called Glyphhanger to automate some of the usecases [3]
