There is always an interpretation of the data, because if you'd only "translate" the raw straight from the sensor to something visible it would look totally green (there are twice as many green as red and blue pixels on the sensor), pixelated and very dark. The raw converter needs to interpolate individual colors for each pixel and at least apply a gamma curve, and adjust color balance away from green.
So, even "linear response" is heavily processed. I think "film standard" is more or less how C1 would show the file if they weren't collaborating with Fuji. Still heavily processed as well but not in line with how Fuji JPG's look like.
I personally like the colors of "film standard" better than the Fuji profiles, but unfortunately there is a lot less latitude in the highlights for recovery. Looks very similar to my old Sony a7 II in Adobe camera raw.
