I would partly agree with you, but then again, we also got Gorgo. I do like Macedon obviously, but it wouldn't matter if it was a one off civ and he went back to Greece. Then again, I'd want multiple leaders so he could be the militaristic one and spread Hellenistic culture.
At that time Egypt was part of the Islamic Arab world, so that makes sense. Speaking from someone that also doesn't mind Cleopatra as a leader, I don't see the need to have a separate Ptolemy Egypt considering it is still considered part of the Pharaonic dynasty period of their history.
I also don't think it's sexist to also want a ruler such as Ramses, or Akhenaten my personal favorite for Civ 7, over Cleopatra either. I can also certainly see why some people would also want Hatshepsut over her too.
