Adobe Fonts
As long as you are logged into the Adobe account, you can find really great fonts on Adobe Fonts. You can access this be either going to fonts.adobe.com or when you are selecting a font within an Adobe product and click on Find More.
Just recently they have allowed people to start using these within websites too. Licensing comes with the Adobe account.
Google Fonts
Google fonts can be downloaded by anyone and are completely free to use. You can find them all here fonts.google.com
Licensing specifics can be found on each font page but you should be okay to use most fonts on there.

Dafont
If you need an abstract font, dafont is probably the best bet. Adobe and Google are great for typical, sans-serif and serif fonts, but if you need something different, dafont will have it.
