This is a pretty deep rabbit hole to go down, and you will find some strongly opinionated people on this topic. You may want to consider the download cost of a font to your visitor in some cases.

That being said here are some good resources:

https://fonts.google.com/ https://www.fontsquirrel.com/

If you're interested here is a catalog of the TeX fonts: http://www.tug.dk/FontCatalogue/

Some advice on internet typography from a TeX perspective (probably not for everyone, favors more information dense layouts): http://www.tug.dk/FontCatalogue/

As for what fonts I personally like Roboto Slab from google for websites, and Gentium for print. I am a fan of serif fonts for text -- I think the sans-serif default for computer screens made more sense with older, lower DPI monitors.

Gentium: http://software.sil.org/gentium/

Thanks, will check the links out.

I'll keep in mind the download cost of a font.
