You're correct on the bullet vs number distinction.  That can't be
completely captured, though - you can say that 'repeating' types are
bullets, but 'non-repeating' may or may not be.  It'd probably
sufficient to just read 'repeating' counter styles and strings used
directly in list-style-type as bullets and everything else as numbers,
though.

It doesn't seem like the distinction between numeric and alphabetic is
important.  They're just alternate ways of representing numbers.
We've already made the point that legal documents, where the precise
marker is important, should use inline text for their markers (which
reminds me that I need to add the
display:marker/list-style-type:inline feature).  In other documents,
the fact that a list is presented as "A" instead of "1" is mostly
irrelevant.  This is styling information, not semantic content.

To further complicate things, counter styles can use images as glyphs.
 These don't have readable content at all (and I'm really not
interested in trying to apply alt text to images specified in CSS).
