Tingis is a beautiful map. It is a pity, that it is limited by oil and second food shortage. With only 15 units of oil, and maximum of 6 luxuary palaces due to lack of meat, you can't even evolve a whole city of required 8000 people to large insulae and higher. At least, if you're not going to stockpile: which is hard, because you're being sold oil, not olives (and there is a cap defined by your population).
Nevertheless, I made a city of 16000 (on the way), mainly of medium insulae. I made a palace district on the plateau. I managed to build only 5 palaces, 3 luxuary, and 2 large, due to lack of space. To relieve some people from the labour market, I added a second patrician block, with large villas. The rest of plebs live in grand insulae (EDIT: only 2 2x2 small casas).
