Another great option and my current favorite is the Source Family from Adobe. They are open source and variable, and have a full family of Serif, Sans and Monospace fonts.
I went there and expected something like comic sans. I was blown away, until I realized I disabled webfonts a long time ago.
I had a proper look at it after that. It isn't even half bad. I never disliked comic sans for the use cases it was intended for, and a derived coding font is a fun project.
