To answer some of your questions:
For in-chord-adjustments we have the \tweak-command.

In your example I'd be fine with adding
\layout { \context { \Voice \override StrokeFinger.add-stem-support = ##t } }
to the score and dropping the extra-offset.
Admittedly the a-finger is higher than the m-finger, but that's
because of different stem-lengths.
This will always happen ofcourse.

Cheers,
