Followup: this requires a bit of math but it works great in practice. I
have a lot more control over the tightening now, which is just what I
needed. Thanks!

Interesting! I didn't think to use kerning directly. Thank you for the
idea!! It makes sense since obviously I am trying to do something a
little more sophisticated than the default "tighten" functionality.
How does "line tightening" pick an appropriate kerning value? I'm
thinking you could use -cellSize to get the actual string width, and
then you could figure out the ratio of cell frame to desired size to
compute a kerning value... but I've never used kerning before so I
could be off in the weeds here.

Gah, I spoke too soon.
This "solution" actually disables tightening entirely. So I'm back
to square one. Please help!
You could try to manually squeeze the result by setting an attributed
string's NSKernAttributeName value, but that would be far from
automatic (since you'd have to be constantly measuring the string,
redoing the kerning, and, in all likelihood, handle the
auto-ellipsification yourself).
It could probably be handled by a transformer in a binding, so it may
not be too bad, though there's no obvious way for the binding to know
the line width it needs to try to shrink the string to...
