A couple thoughts.
First is that "all things are relative" and second is that "each medium has its own pallet".
So to the first point, I find that if I want colors to look richer, that printing slightly darker helps, this isn't really changing the saturation but is changing the relationships of the tones to our world. Conversely by printing slightly or even significantly lighter you can make things look more pastel. These effects can be applied locally or globally and this can control detail too. The other control I find fun here is color balance. For example in the real world cars that are supposed to be "red" many times lean toward orange, red, but too yellow for my taste. I can print it with more blue and by my standards "improve the red". Similarly you have to decide which version of real color you want. If you are shooting in a bar where the lighting is warm, do you really want destroy the mood and reality of the scene to correct the skin tones to studio perfect normal? I'm not suggesting one or the other is the right way, simply that both are actually, truly, and absolutely correct answers, your preference is the judge.
Second is the color pallet thing. I really enjoy Portra, and I enjoy Superia, and Fuji Pro films, and have done shots I really like with Kodak disposable cameras that I didn't know what film, other than ISO, was inside. Unless you have very specific expectations you will find that most films give very good results. Sure, if I do a wedding gig I'm probably going to order fresh Portra for the job but if the shipper runs over the package with a forklift I'd happily reach into my fridge and grab 20 rolls of 5-year-old Superia 400 and do the job. What I understand is that most of the problems I have with any film are failures on my part, say scrimping on exposure or forgetting to set exposure or setting exposure without remembering that I have a polarizer on or not considering that films respond to different colors differently so in that bar under nice warm light I might forget that I need a bit more exposure. Did I mention exposure?
