I think the best way to ask this question is what is the
correct '-f type' to use for extracting any chunk of data
from a video container.

Seems like '-f data' is incorrect.

The reference to DTS suggests ffmpeg imagines the data
stream to be an audio stream.

http://DavidFavor.com/data contains the VOB file.
