The main issue with high population is not that it's not beneficial to have (it is), but that there are often no terrain improvements that can make these citizens productive enough.
Neighborhoods should be workable and their yields should be 2 of each yield that the city has a district for. Thus, if you want a monster city, it becomes potentially powerful, but you'd really need to focus on growth and invest heavy hammers into neighborhoods and districts.
And then, having 'hood upgrades that provide food OR tourism would make sense (either you want an even bigger city or you want tourism).
