Maybe I could reframe the question. Catholic Answers writes this:
"During the Reformation, primarily for doctrinal reasons, Protestants removed seven books from the Old Testament: 1 and 2 Maccabees, Sirach, Wisdom, Baruch, Tobit, and Judith, and parts of two others, Daniel and Esther. They did so even though these books had been
regarded as canonical since the beginning of Church history."
1. Is the above statement true or false, and why?
2. Is the above acceptance of the deuterocanon the correct one, or is it correct to acknowledge the apocrypha as useful, but ultimately lesser than "Scripture"?

Its a false statement.
The reason certain books were not considered as God-breathed (canonical) is because the valid line of prophets had ceased about Artaxerxes time. Josephus who overlapped the times of the apostles the beginning of Church history wrote this.
"8. For we have not an innumerable multitude of books among us, disagreeing from and contradicting one another, [as the Greeks have,] but only twenty-two books, (8) which contain the records of all the past times; which are justly believed to be divine; and of them five belong to Moses, which contain his laws and the traditions of the origin of mankind till his death. This interval of time was little short of three thousand years; but as to the time from the death of Moses till the reign of Artaxerxes king of Persia, who reigned after Xerxes, the prophets, who were after Moses, wrote down what was done in their times in thirteen books. The remaining four books contain hymns to God, and precepts for the conduct of human life. It is true, our history hath been written since Artaxerxes very particularly, but hath not been esteemed of the like authority with the former by our forefathers, because there hath not been an exact succession of prophets since that time; and how firmly we have given credit to these books of our own nation is evident by what we do; for during so many ages as have already passed, no one has been so bold as either to add any thing to them, to take any thing from them, or to make any change in them; but it is become natural to all Jews immediately, and from their very birth, to esteem these books to contain Divine doctrines, and to persist in them, and, if occasion be willingly to die for them."

Why anyone would think that Christ and the apostles would add to the OT canon is beyond me.
To be clear, however, what some looked for per Malachi, etc about the forerunner became fulfilled as the last prophet rose up (John the Baptist). From then, we have the NT.
Melito circa CE 170 made a list that's the same as the canon today sans Esther. He wrote this quoted by Eusebius.
"14. Accordingly when I went East and came to the place where these things were preached and done, I learned accurately the books of the Old Testament, and send them to thee as written below. Their names are as follows: Of Moses, five books: Genesis, Exodus, Numbers, Leviticus, Deuteronomy; Jesus Nave, Judges, Ruth; of Kings, four books; of Chronicles, two; the Psalms of David, the Proverbs of Solomon, [also known as] Wisdom also, Ecclesiastes, Song of Songs, Job; of Prophets, Isaiah, Jeremiah; of the twelve prophets, one book; Daniel, Ezekiel, Esdras [Ezra/Nehemiah, maybe Esther]. From which also I have made the extracts, dividing them into six books.” Such are the words of Melito."
