Fuji Film Stocks for a Super 16 Commercial: Which to Choose?

[illia]

I have to shoot a commercial on Super 16 format and with Fuji stock, as I'm new in cinematography (was a photographer and videographer).
In tungsten-balanced Fuji film stocks I found two different areas, the F classical stock and the Eterna stock. I would like to know if there's any important difference such as grain structure, dynamic range and so on.
As we'll shoot on Super 16, I would also like to know if anyone has any experience shooting with high-speed stocks for TV release (and telecine process). Is the grain too obvious for a classic TV commercial look? Do I have to choose any slower stock? I would like to use Kinos, so it's important that I have enough sensitivity to register subtle light sources, but the room I have to light is small, so I guess a slower film should be OK.
Is either of those stocks a better choice for telecine?

There is an advantage in using the slower stocks in S16 even for telecine -- if you can, I'd use Eterna 250T instead of 500T.

The Eterna line-up is finer-grained, wider-latitude (lower contrast, softer blacks and colors) than the old Super-F series.
