Yeah, Sargon for Sumer makes no sense to me.
Akkad was a different empire entirely, and the culture was also very meaningfully different (entirely different and unrelated languages for instance).
I think there's a lot of different material to pull from to differentiate Akkad too. Sargon could have a big militaristic, conquest focus, and the civ ability could be something dealing with empire management. After all, Akkad was the first real empire in the world (in the sense of centralized control over more than one "nationality").
I'd really like to see Akkad in Civ 7, actually.
True, but Sargon would make a decent substitution for both Sumer and Babylon, combining elements of both (warmongering leader for a Civ that is good at agriculture and science), and leaving room for Assyria (which can be an expansionist civ that is good at economics and culture). You'd get him specifically so you don't need to include Sumer and Babylon, and can introduce a different Civ from the area.
And I agree that he should lead the Akkadians, and not the Sumerians. Make it happen.
