My apologies for not including my file (similar to yours above) which
illustrated the problem with \abs-fontsize.

Just to complete the circle, as it were, I have now discovered a
downside to using \magnifyStaff.  In the (hopefully) attached image,
you will see that the tenor clef sign in the 1st cello has an enormous
space after it.  I cannot produce a minimal example to illustrate this
problem, because weirdly the size of the space seems to depend on the
number of other staves on the page!  If I remove all the other staves,
the space is still a little big, but not nearly as much as this.  Every
such in-staff change of clef produces a similar result.

Changing back to set-global-staff-size has cured this problem.

Back to the drawing board now for my title pages etc.
