With the uninitialized variables fix, the remaining issues might just be
due to bad default settings (see below). I would appreciate help in
finding good settings because I don't deal with choral or orchestral
scores very often.

Try increasing 'space, 'minimum-distance or 'padding in
top-title-spacing (\paper block).

Y-extents aren't used any more for spacing. You can make the lyrics
closer to the staff by changing
Lyrics.VerticalAxisGroup #'inter-staff-spacing
In particular, try decreasing 'space and 'minimum-distance.

This is controlled by the between-system-spacing \paper-block variable
(try increasing 'space).

Is it a \mark? If so, its alignment is measured with respect to the bar
line, not the note (and so the tighter horizontal spacing makes it look
further to the right when compared with the note). If it's a TextScript,
I have no idea what's causing the difference.

Thanks for the continued feedback,
