Reviewing yours:
> * They were never included as part of the Hebrew canon of books
There is no evidence that there was a closed Hebrew Canon prior to the time of Jesus.
The Hebrew scriptures were divided into three parts - The Law, the Prophets, and the Writings. While it's true the Law and the Prophets had solidified by the time of Jesus, there is no evidence that the Writings were closed, and every reason to indicate that they weren't (see Rabbi Akiba and his comments regarding Sirach, Esther, and the Gospels around 100 AD).
> * There is no evidence that they were included in the original versions of the Septuagint
I'm not sure why you think that is relevant?
> * Historian Josephus made clear that those books were not part of the canon

> * Not one New Testament writer quoted from the Deuterocanon
Numerous Old Testament books, like Esther, that Protestants believe to be inspired are not quoted in the New Testament - does that make them not canonical?
Numerous non-canonical works, like the Book of Enoch, are quoted in the New Testament - does that make them canonical?
And anyway, it's interesting to know that the original KJV of 1611 (which included the Deuterocanon) included 11 cross-references in the New Testament to Deuterocanonical books, where it believe New Testament authors were quoting from or alluding to parts of the Deuteronincals.

> * Early church fathers did not consider them part of the Bible canon
This is inaccurate, look at the historical record: https://christianity.stackexchange.com/questions/80280/which...
> * John Wycliffe, a catholic who included these books in his translation, still did not consider them of the same authority as the rest
"As Jerome saith" echoed down through history. Jerome, around 400 AD, mistakenly had some doubts, and those same doubts reverbated over the next thousand years. Both of Jerome's two core reasons for his doubts are now known to be wrong.
> * Even the council of Trent did not accept all the “apocryphal” books (e.g. 1 and 2 Esdras were excluded)
Not exactly. https://www.patheos.com/blogs/davearmstrong/2020/06/1-esdras...
> * The content of the books testifies against themselves with their inaccuracies, contradictions, and other problems that are not found in the traditional Bible canon
Actually that's not the case - their "problems" are the same as those from the rest of the Protestant canon. See https://youtu.be/tRmlW954PwI?t=651
