There are many solid videos available, however I agree that some kind of "sensible order for one to progress through them in a sensible manner." is needed.
One way I imagine it can be done is a step by step tutorials of actual song making. Explaining and auditioning items on the way. 3 songs... but not trying to throw a bunch of chords to make them "sound" like a song, but actually reverse engineer already made song. Intro, chorus, verse and all that good stuff. Efficient workflow is the key!
1)Basic tune - 10 minute video.
2)Intermediate tune - 15-30 minute video.
3)Advance tune - 45-60 mins.
Perhaps with links within a video to already created tutorial content, if one wants to expand the knowledge on particular topic.

There is a one item that I think should be waited out for
Is when Utility tracks gain more controls as legacy tracks.... One of my biggest challenges with BIAB was and still is in a way, are the actual variation for specific parts. Limit is, that there were not enough tracks to do them on the fly (yes, there are workarounds, Hi Charlie)...but they are very counter intuitive, take long time and are not fluid as the whole concept of composing/arranging with BIAB. With Utility tracks, it got much better, but not there yet.
To me these Utility tracks, when they become fully flexible, are the missing piece of the puzzle to do most of composition work, trying out new things (not losing others) without leaving BIAB.
Ok, enough of my blabbering. Couple of years back I requested a workflow video and I believe Kent done a decent job on it. The only thing I didn't like is that he used "classic" (colorful) interface instead of minimalistic, but still it should totally work as Introduction to making a song in BIAB - Intermediate.
