IIUC, all of them. So...
I started wondering about this after one of the carparks you mentioned in
Quantico recently showed capacity 15, with 11 car spaces + 4 motorbike
spaces. Should that be =15, or =11 + 4?
...15. Rationale: existing capacity:* spaces are not usable unless you
meet the criteria, but are (AFAIUI) included in capacity. The
description in JOSM is explicitly "capacity (overall)". On the wiki, it
is "the number of vehicles a facility holds". Both imply total capacity,
including spots that aren't usable to many vehicles. It seems clear that
the intent is that "general" capacity is the overall capacity less any
capacity:*.
It's possible that some software will need to adapt (though I question
how critical it is to know capacity, since no software can know how many
spaces are already occupied), but it's also possible such software is
already not honoring other, existing capacity:* tags.
So, do we have a shopping centre parking lot with capacity=100, or should
we have capacity:"vehicle"=60; capacity:motorbike=10; capacity:disabled=10;
capacity:prams***=6; capacity:ev_charging=4;
capacity:(temporary/short_term/click'n'collect)=5; capacity:loading=5
Hmm, "loading" would be good for curbside pick-up, though now we're into
the discussion of whether a space for standing-only is actually a
"parking" space :-). As for the main thrust of your question, see above.
***=prams - I'm not sure if they're yet a thing in OSM?, but that's
carparks marked as reserved for parents with prams eg

Yeah, that might make sense. I'm not sure if it's better to go ahead and
add that, or if we should treat each type as a separate proposal. (I'd
almost be tempted to yank "compact" again and resubmit it as a follow-up.)
