I know this is borderline insufferable, but Pluto is a dwarf planet. Moons don't orbit stars, they orbit planets (and dwarf planets, which is how Pluto itself can have ~5 moons).
I'll be the first person to hate on Jupiter (failed star ass) but everything that shares an astroid with Jupiter is locked into that position by Jupiter's gravity. Therefore it is gravitationally dominant, or has cleared it's orbit.
Admittedly Charon is almost half of Pluto's size (and is thereby itself sometimes considered a dwarf planet rather than a moon), but the other moons are more than an order of magnitude smaller, which is a greater proportional difference than the one between Earth and its moon (roughly 6:1).

I have no respect for a celestial body that can't even clear it's orbit of similarly sized objects.
Then Jupiter is a dwarf planet.

IMO Pluto–Charon is definitely a double dwarf planet system. And I've seen arguments that Earth–Moon should be considered a double planet.
I support both theses but didn't want to get too far into the weeds.
If Pluto isn't a moon, why is its barycenter in space?
I'm kidding, I know it's dwarf planet within a binary system.
