Impedance of open wire feeder using multi-strand wire?

But I take it that your picture still applies to single-core conductors,
and very fat conductors at that.

Correct.

With the feedline I have in mind, S=55mm and d=1.2mm, so S/d=27.5, which
is way off the end of the scale in your picture.

Then your approximation formula will be fine.
