Below are the semantic definitions for archival, bond and cotton media-type values we are proposing. The media weight (i.e. gsm range) can be ignored since the PWG does not include it in “media-type” definitions. I included it because it was available to me from production printing.
FWIW, we already have "stationery-bond" as a media type, and in general I would prefer to avoid mixing top-level and suffix names. More comments inline below...

Extraneous materials (such as sugars, starches and gums) in the pulp that can cause discoloring and deterioration, are carefully removed. Physical strength for the paper is ensured by using a long, high quality fibers such as cotton or flax that enables it to be usable for long periods. (gsm range 106-169)
Given that the existing photographic media type are often/typically archival-quality, would it make more sense to treat "archival" as a common suffix for existing top-level types, e.g.:
cardstock-archival
labels-archival
stationery-archival
???

As I mentioned above, we already have stationery-bond.

Do we need a top-level for this too? "stationery-cotton" (and, if you think it is necessary, "cardstock-cotton") would seem to capture the existing usage for this type of media.
