Type IIs
Type II civilizations didn't advance without technology. If a civilization can manage to build a Dyson sphere, what was that planet's social and environmental cost? Did they figure out how to handle pollution from developing that technology? And once they solved all those problems, who would it serve? A planet crammed with people, or just elite tribes? As suggested in Limits to Growth , constrained growth is the key. Type IIs would have figured out overpopulation, such that there were a system of checks and balances. They would have solved the system feedbacks, delays and overshoots. Their planets (plural, because they would have access to many) would probably not be very populated, meaning there would be more than enough resources and wealth (or however that concept was understood) to go around.
