these questions are very difficult to answer in a general way, because it depends a lot on workflow and personal taste.
are you doing analog prints or planning to scan the films?
if you're scanning, then the scanners color rendering will actually make a bigger difference in colours than the film stock itself.
Very broadly said, Kodak Ektar is quite difficult to scan in general, Gold 200 usually will tend towards a more monochrome yellow/orange look, and Fuji Pro400H will emphasise blue/green more (the Fuji is also quite hard to find now).
my personal preference in those situations would be Kodak Portra 160 as I prefer the colours over the ones you mentioned. It's also easier to scan/print and has fine grain in case you want to make larger prints.
But the best is probably shoot a roll of each, run it through your prefered workflow and see what works best for you.
