Oh, I'm a dumb dumb.

Your issue is that the padding between staff and markup is using the 
bottom extent, not the baseline, hence it looks off.

You might just want to clip the descenders on offending lines.  Not 
recommended for general use, but try:

%%%%
\version "2.19.82"

#(define-markup-command (trim-descenders layout props args) (markup?)
  (let* ((stencil (interpret-markup layout props args))
         (x-extent (ly:stencil-extent stencil 0))
         (y-extent (ly:stencil-extent stencil 1)))
    (interpret-markup layout props (markup
      #:with-dimensions x-extent (cons 0 (cdr y-extent)) args))))

\fixed c'' {
  \override Fingering.font-name = #"Alegreya"
  \override Fingering.font-size = #4
  g8-\finger "q"
  g8-\finger "x"
  g8-\finger "b"
  g8-\finger \markup \trim-descenders "q"
}
%%%%

Side effect is, of course, overlapping.  But the padding should now be 
relative to the baseline (Y-coord zero) regardless of descenders.
