 If the Cancel button is submit=true, the document still gets uploaded even if you null the documents variable. One way to tackle it is to delete the uploaded documents in process when the user clicks cancel.

 This shouldn't upload the document, unless if you have something like wizard style form etc. In those cases you can delete these stale docs and terminate the process on a timer.

 nope. it will prevent the document ID from being passed into the process, but will not prevent the document from landing in the target folder. the only viable methods I've found to handle this are to either disable the "cancel" button, or to have the SAIL form track "newly uploaded" document IDs and pass them into an "orphaned doc IDs" list when Cancel is clicked, then have a special flow in the process to delete orphaned documents. 
 Edit: of course I replied before reading the rest of the thread. Did your tests eventually bear this out? In the (not very distant) past I've tested this extensively, but maybe not within the previous 2 or 3 Appian versions, in case anything's changed.
