You could add the Rocky Mountain Reaper, Propain Yuma, and Trailcraft to the list. There is also a good chance that some other options will become available.
Sounds like you are doing the same thing I was, spreadsheet of geometry and specs. I really wanted my boy to spend more time on 26, he still could as we have some in the collection, but we let him be involved in choosing his next bike. He's 11.5 years old and just now hitting 4' 8" and it seems like he would be likely to outgrow the 26 quickly. The XS Transition Scout we just got is tiny (and heavy) but the wheelbase is long. For the type of riding he does the YT looked good for the present, but he's not interested in the brand despite being him being an AG fan. If one had been available I probably would have gotten it anyway. I do like the looks of that Scott, but that tiny rear shock makes me question the kinematics and since he is a sender I'm not confident in it. I also like the Chromag Minor Threat, but he doesn't. He was most interested in a XS Trek Fuel and the Propain Yuma but this had more to do with their sponsored riders than anything.
Not much help but I will say despite the current shortage it's a lot funner now to pick out a pre-teen bike than it was in the past. Good luck!
