These are easily imported via CSS:
- [Merriweather](https://fonts.google.com/specimen/Merriweather)
- [Atkinson Hyperlegible](https://fonts.google.com/specimen/Atkinson+Hyperlegible+Next)
- [Figtree](https://fonts.google.com/specimen/Figtree)
- [Roboto](https://fonts.google.com/specimen/Roboto)

These require a bit more legwork but are also possible to get working in Obsidian Publish:
- [iA Writer Duo](https://github.com/iaolo/iA-Fonts/tree/master/iA%20Writer%20Duo)
- [Heliotrope](https://practicaltypography.com/heliotrope.html)
