Along with Sedna, Orcus, Haumea, Makake, Eris, and Gonggone (among others)?

Yes. If they are in hydrostatic equilibrium, rounded by their own gravity, they are planets of the dwarf planet subcategory.

As is Pluto. Why then the call to make Pluto a planet “again” when it is already a dwarf planet?

Because the IAU definition specifically says dwarf planets aren't planets at all but another type of object entirely. This is contradicted by the Dawn mission to Ceres and the New Horizons mission to Pluto, both of which showed these worlds to have planetary processes and geology similar to those seen on the terrestrial worlds.

What about planetary mass moons such as Titan, Ganymede, etc.? Should they be classified as planets as well?

Well let's just make everything a planet then. Do you have a cat? Let's make it a planet.

My cat is a goddamn super earth. Diets are ineffective.

If your cat was a super earth then we'd have a 3 body problem here.
