Actually, I have no idea why the Council of Trent felt they needed to address the issue again. Maybe the Council of Nicea failed to anathamatize anyone who disagreed with the list. I don’t much care and can’t for the life of me see how it could matter to the discussion WHY they did. But your assertion, “... Catholic scholars prior to Trent feel free to debate the canon status of books ... “ is at least wrong; Jerome certainly felt obliged to obey Nicea. Perhaps Walafrid Strabo was simply ignorant on the matter because his source for the Nicene Council omitted the list.
But if you’re suggestion is that the Council of Nicea didn’t publish such a list and that St. Jerome, who was intimately familiar with the Council was wrong about it, (it is missing from our currently surviving document) then you are obviously continuing to ignore the Council of Florence, another ecumenical council uniting not just Roman Catholics but Orthodox as well, which held that it was binding doctrine throughout the history of the Church that the deuterocanonicals established necessary doctrine.
>> Jesus gave what He considered scripture, and the Glossa Ordinaria agreed with Him and Jerome. <<
Never. And if you suppose that because Jesus never quoted five of the seven books in question, you should know that he also never quoted nearly half of the Old Testament books, including most of the Khetuvim.
“But your assertion, “... Catholic scholars prior to Trent feel free to debate the canon status of books ... “ is at least wrong”
No.

Even the Council of Trent refused to make a decision, as I’ve already pointed out to you, concerning the status of the Apocrypha and what was meant by “canon”.
Nicea did not address the canon:
