Not all list questions are disallowed. As noted here, the main issue is with open-ended lists, which tend to be too broad and to accumulate single-item "me too" answers:
It’s not reasonable to ask a question on a Q&A site that requires
knowledge of all works that ever existed, and then request a massive
list of the works that contain one specific element. This sort of
question lacks a single, finite answer. In practice these questions
accumulate a steady flow of “me, too” answers where people add a few
examples in a new answer.
And similarly, as noted in the consensus answer to a newer question:
By themselves, “long” list questions from a specific small domain
aren’t necessarily a problem; unless a specific question attracts
1-item answers instead of a comprehensive list.
A list with a short, finite scope, such as the list of all (Legends and canon) Star Wars backstories for the theft of the Death Star plans, could be on-topic. But it depends on how it’s asked, and what sort of answers it’s seeking. A question that asks for a full summary of even a single account of how the Death Star plans were stolen (e.g. Rogue One) could be too broad, and it seems like you might be suggesting that sort of question, based on wanting something “more fleshed out than the wiki pages.”
On the other hand, a question like “How many different versions are there of the theft of the Death Star plans?” would probably be perfectly fine. There shouldn’t be more than a handful, so it would be a nice, finite list. But a good answer to this question wouldn’t necessarily contain a full summary of each novel, radio drama, and movie that detailed the theft of the Death Star plans.
If you really want to write a point-by-point summary and comparison of the various stories of how the Rebels acquired the plans, on the other hand, there might be a place for that on the blog, which allows for long-form writing free of many of the restrictions of the Q&A format.
