Unfortunately, as Catholics, aside from the two Bibles you already have there aren’t many more choices. Our Protestant brethren have dozens of study Bibles available to them.
Like many have already said, the Didache RSVCE2 version is probably your best choice.
There are quite a few study Bibles based on the NAB, but in my opinion (and many others), the footnotes are so terrible that I’d stay away from the NAB completely. Also, many “student” and “youth” Bibles seem to emphasize “social justice” issues in their special topics sections, while really skimming or completely skipping over topics concerning sexual morality.
