Was there any interesting additional information in those commentaries?
To be honest, not so much. It's basically just "Yeah, we thought it would be neat if this happened." I guess there's some stuff about their inspirations, like how mixed martial arts inspired pro-bending and so on, but nothing that you can't also get from the Avatar Wiki and online articles. So it could be informative if you've read nothing about the show online, I guess.
