Can you give us some Magisterial texts to back up our claims? I mean your claims that invincible ignorance does not apply to “Catholics, non-Catholic Christians, Muslims, Jews, etc. etc.” Good luck with that.
Basically, you’re saying that invincible ignorance does not exist since it applies to no one.

“Outside the Church there is no salvation”
CCC 846 How are we to understand this affirmation, often repeated by the Church Fathers? Re-formulated positively, it means that all salvation comes from Christ the Head through the Church which is his Body:
Basing itself on Scripture and Tradition, the Council teaches that the Church, a pilgrim now on earth, is necessary for salvation: the one Christ is the mediator and the way of salvation; he is present to us in his body which is the Church. He himself explicitly asserted the necessity of faith and Baptism, and thereby affirmed at the same time the necessity of the Church which men enter through Baptism as through a door. Hence they could not be saved who, knowing that the Catholic Church was founded as necessary by God through Christ, would refuse either to enter it or to remain in it.
CCC 847 This affirmation is not aimed at those who,** through no fault of their own, do not know Christ and his Church: **
Those who, through no fault of their own, do not know the Gospel of Christ or his Church, but who nevertheless seek God with a sincere heart, and, moved by grace, try in their actions to do his will as they know it through the dictates of their conscience - those too may achieve eternal salvation.
CCC 848 “Although in ways known to himself God can lead those who, through no fault of their own, are ignorant of the Gospel, to that faith without which it is impossible to please him, the Church still has the obligation and also the sacred right to evangelize all men.”
CCC 847 is about invincible ignorance.
Assuming no lack of mental ability, by definition Catholics, non-Catholic Christians, Muslims and Jews know something (in varying degrees of knowledge) about Christ, his Gospel, and his Church so it cannot apply to them.
Those who know something but refuse to learn more or learn more and reject Christ and his Church will not be saved.
Those who know something and want to learn more (say going through RCIA) and live according to Christ’s teachings are said to have a Baptism of Desire (Explicit).
Those who know something and want to learn more but are denied the opportunity to do so but live as best they can in accordance with Christ’s teachings would also fall under Baptism of Desire (Explicit).
Invincible ignorance implies no knowledge of Christ, his Gospel, and his Church but nevertheless living in accordance with Christ’s teachings (Baptism of Desire - Implicit).
