I'd say fuji has a slight edge due to the 4layer emulsion. Same applies for Superia 400, you could try it first if you don't want to pay the meme prices for Venus and Portra 800.
Here's how Superia 400 looks in a mix of tungten-like lights, with natural light in the background, "uncorrected" - i.e. balanced for the natural background light.
It's very usable and can easily be edited for neutral skintones. Of course if you mix sources, you balance for one source, and the others turn to crap, but c'est la vie.
Then there's the niche option of using a tungsten cine film like 500T, but only if you can find it (*and* correct ECN-2 processing) at a reasonable price, I wouldn't bother with Cinestill.
