If so, would it be best to use a neutral style to get the "most accurate" histogram if shooting raw only? Or does it not matter?

A flat picture style will give you more accurate histograms when shooting raw. Typical color processing will apply strong contrast curves and color saturation, which tend to blow both ends of the histogram.

There is a highly specialized white balance setting called UniWB, which keeps the native sensitivity of each of the three color channels: in daylight conditions, both the red and blue channels are normally greatly underexposed giving a UniBW image a strong green color cast, but this shows the histogram more accurately. For example, blue skies may appear to be overexposed, but they are not in the raw blue channel. Using UniWB is complex however, as is getting in in the first place.

Ciné profiles are often extremely flat.
