There we’re getting to the heart of the matter: opinions of theologians and “teachings” of Magisterial authorities below the level of declaring what is of the deposit of faith (through either the extraordinary or universal, ordinary Magisterium) - while they are owed obedience and assent as the default and initial response in respect of their position, to what extent can they err when the deposit of faith, what must be believed to be saved, is not involved?

Tuas Libenter, what Pope Pius IX said about this.
He said that while we are bound in conscience to obey the dogmatic decrees of the Catholic Church, we are also to submit to, not only the Church's Universal Magisterium, but also her Ordinary Magisterium when the teaching is said to be divinely revealed:
"...this submission must also be extended to all that has been handed down as divinely revealed by the ordinary teaching authority of the entire Church spread over the whole world, and which, for this reason, Catholic theologians, with a universal and constant consent, regard as being of the faith [...] they must, besides, submit themselves, whether to doctrinal decisions stemming from pontifical congregations, or to points of doctrine which, with common and constant consent, are held in the Church as truths and as theological conclusions so certain that opposing opinions, though they may not be dubbed heretical, nonetheless, merit some other form of theological censure".
The "universal acceptance" opinion of some theologians from the last 150 years or so do not come close to meeting this criteria.
