I prefer a unit. It would provide flexibility if you wanted to be slightly
larger or smaller than the font's cap height. And it would match the
existing ex and em units.

The flexibility might also accommodate non-Roman script usage if cap height
is not exactly the desired length. I know that some Hebrew fonts are created
with Roman glyphs and a Roman cap height, then the Hebrew glyph height is
set to something smaller than Roman cap height. Knowing that ratio you could
use a fraction of the Roman cap height to match the height of the Hebrew
glyphs.
