Question about Formatting & Organization

[Markit]

I've been wondering about this for a while, but are there an "official" (in the sense that the moderators approve of them) formats by which movie, TV, and video game pages should be organized? I bring this up because of my discussion with AdAstra2009 in the District 9 page, since I feel the previous format of having categories based on type with weapons listed within them chronologically is more clear than simply having them arranged in chronological order without categories. There's no specific means of organization that is listed in the rules page, so I was wondering whether anyone would like to clarify what is or isn't an "appropriate" format.
