Checking quickly:
- coastal city south of capitol to grab fish and horse - you can't work the fish from other locations anyway. Can work two scientists for example, or you can later workshop some plains tiles for extra hammers. Or cottage them and work them powered by fish.
- gold city 1S of the gold, gets fresh water from lake and can use corn to work the gold and grow. Has some grasslands for cottaging as well.
- western coast could hold a strong gp farm with four food specials - after CS when you can chainirrigate the wheat it can go up to 8 specialists working four food tiles.
None of the above catches the sheep, but the map doesn't show what else is on the tundra. If there's something nice like furs or silver, you can use the sheep to work those. And the wines.
