You might be interested in something from Paradox games; they make a lot of grand-strategy games. I played some earlier version of the Crusader Kings--it's interesting in that you play as long as your line does run out. As long as you have an heir, you keep playing. They have many, many more.

You might like Civilization, though the new one has been getting lesser reviews.

If tactical/strategic is acceptable, Phoenix Point, XCOM, XCOM 2 are fun. They have a strategic/economic aspect, but the main focus is turn-based squad v squad missions on different maps.

Grand Tactician: The Civil War 1861-1865 is a strategic game. You can play the tactical battles, or auto-resolve them. I played it years ago in early release and decided to wait until it had more polish; but I never did. I generally liked the game, then.

I do not know the availability of all of these on Mac, but I suspect you could find most of these.

I do recommend that before you buy, you watch a YouTube video of someone playing it to see if it is what you are looking for.
