I've not run into a population cap, instead I've run into an object cap. One of my most long term cities currently has over 750k residents in it, but the only way I was able to achieve that was with some mods. One of the most important is a mod that redefines the death rate of citizens. This was probably one of my biggest frustrations in the game, having to deal with massive death waves. My research on it concluded that apparently all sims have an exact age length in the game. So the problem ends up being if you end up zoning any type of high density residential in even remotely good size areas, every single one of the 2-10k citizens that move in in the next month or so will all die at the exact same time. This is something I wish the game devs themselves would fix instead of forcing users to apply mods to have a functional city. Here's a graph of how that mod changed it up to what I would consider a more realistic algorithm.
The other mod I had to use was one to expand the territory beyond default allowed. But before I was able to actually fill it all I got an error saying "cannot create anymore objects of this type" across every build able option in the game.
