Documentation for style value to assign to properties

I have a hard time finding documentation or some kind of list of values to assign style properties.

This is setting the the text of label to bold
new Setter { Property = Label.FontAttributesProperty, Value = FontAttributes.Bold }

but I can't find an example of setting the font family
new Setter { Property = Label.FontFamilyProperty, Value = ...?

It would be nice with a list of all the controls style value. (Sliders, Buttons, Labels etc.)
