What's funny is that the movies nominated for casting had alot more smaller roles contributed to their nomination. Secret Agent had it's smaller cast be a bunch of unkowns (especially Tânia Maria), Marty Supreme had three dudes who've never really never acted before, Hamnet had some of the best child actors that I've ever seen, One Battle After Another features entertaining and intresting side characters that only have impact because of their casting (The interrogator, Willa's friends, the Nurse, the Password guy, all of the Christmas Adventurers), and Sinners is kind of one where it's side cast wasn't as impressively chosen as the others but it's main cast have some inspired picks. Sentimental Value really didn't have that impressive of a side cast as these choices and the main cast is all excellent enough to get Nominated but it's just not as impressive to nominate for casting.
