There are several approved Bibles for lectionary and personal use, but the only āofficial Bibleā of the Catholic Church is the Latin Vulgate. Iām sure you wonāt be reading that.
Usually, people tend to pick whatever Bible edition is used by their particular diocese/episcopal conference for lectionary use, out of sheer convenience of being able to directly correlate what they hear at mass to what they read at home. Some others prefer to choose the editions they think are more correct or more suited for them. However, the very a Catholic should do is ensure that that the Bible is a āCatholic editionā (meaning it contains the deuterocanonicals in canonical order), and it has an imprimatur from a bishop in good standing with the Church.
Beyond that, I would be venturing into the hazardous territory of which Bible edition is better. Itās a minefield, that topic.
