CA Superman most likely solos. The large majority of the team Marvel shown, are only universal (Eternity, ..) or sub-universal (Celestials, Watcher, Galactus, ...) in scope.
^ Clearly someone who has never read/understood Superman Beyond.
Not that I'm suggesting CA Supes would solo Marvel (though it certainly could solo Hickman abstracts IMO), but you don't seem to understand what the Cosmic Armor represents.

------------------------------------
Since they operate on 4th Wall levels I never intended to use them
as part of Marvel's Cosmic arsenal,
but they are canon and this is the make-up of their characters so ...
it is what it is ...
and that is ... Eulogy & Expediency = TOAA
(Eulogy would be the writer, and Expediency would be the artist, or a mixture of both)
That's what I got from the story,
I later learned Marvunapp agrees with my notion.
Anyway ...
First Eulogy pops up disguised as a geeky comic book store owner,
funny how Captain Marvel was an issue there.
He's there to shut down the Captain Marvel Reality (comic book run)
Here,
even Eulogy's clean up crew, has authority/power over Genis.
One of them takes Genis' uniform and replaces it with a jump suit
without Genis even realizing it.
