Every game you listed has very asymmetric civs, AOE4 does not reach that level.
Yet AOE2:DE, the game that inspired AOE4 is using this system.
I enjoy different civs on different maps. Even with civ selection after map reveal most civs can be used and depend on your playstyle, so it does not go against your point.
By picking the superior strategy and having the better game plan, you don’t need to be artificially put in suboptimal map types to show your skill.
This is just SC2 talking out from you, but as many need to underline that this is not AOE2, it also is not SC2. And no, I am confident enough to say that I crush most players with the Delhi Sultanate on land maps, but I would pick another civ if there is a significant portion of water involved.
It should though, this game tries very hard to attract new players and casuals alike to play this game, so you should only deal with such rules at a high enough level.
Since there are two threads having almost the same discussion, I will just quote @sailingship17 here:
