\caps is basically just an alias for \smallCaps which is the so-called 
"poor man's" small caps.  It appears to require the immediately 
following argument to be a string in order to work.  It will not be able 
to traverse to the string behind a \bold for instance.

\fontCaps sets the font-shape to 'caps, which means you need a font 
installed that supports that font-shape.  This is not the same thing as 
OpenType caps, from what I can tell.

\override #'(font-features . ("smcp")) is the (only?) way to use 
OpenType features to select small caps.
