@Multichill and I have started brainstorming this among the both of us, and we discussed (among other things) the following things to take into account:

• P31 for media files helps to make files more discoverable, can be used to inform the kind of infobox templates to use, and in the future can also influence constraints and be connected to Shape Expressions.
• Precision and correctness are important, but it's also important to keep this quite simple and understandable for end users
• It would be nice if there's a limited amount of options for P31. More in-depth characteristics of a file can also be covered in other properties and in qualifiers, etc
