fonts is about fonts and how to use them. It deals with questions about changing family, shape and weight of fonts, but also with font packages.
For choosing a font, the LaTeX Font Catalogue is a very useful resource. If you are interested in installing a new font, perhaps the font installation guide can help. Though be warned, installing fonts in LaTeX is not trivial.
For using a font locally, see How do I use a particular font for a small section of text in my document?.
