What would your production civs be?

It seems like civ 7 has made a lot of efforts to avoid overt bonuses to production for civs compared to civ 5 and 6. Though that does change in the industrial era (modern, but we know its industrial) with America, Prussia, Russia and Meji Japan.

But in the ancient and exploration ages what would be your go to civs for bonuses to production or generally for smooth building experiences?

The only one that really comes to mind is Maya's broken bonuses to production from their unique quarter bonus.
