I haven't even tried because I figured it would be impossible. I think I may wait for a hardware refresh, if I get one at all. I haven't been playing my Xbox Series X a ton just because I have so many games to play on my PC, and it's hard for things to seem next-gen compared to PC. I do like the possibilities of the DualSense controller, so I hope that level of haptic feedback becomes an industry standard. Like your son, I would want the version with the disc drive. I would never want to be locked into digital purchases, even though the bulk of the games I own are in my Steam library. With consoles, I get physical copies whenever possible because I like being able to pass them on to my nephew or whoever when I'm done.
I wish you luck. Bots+scalpers are really making life hell for normal people these days. I still want a new video card, but who knows when those will be readily available, either.
