Forgive my ignorance

I totally agree with your last paragraph.
However, it is wrong of you to refer to changes in Church discipline regarding the ordering of the Sacraments as ‘disorder’.
This is not ‘disorder’, any more than the change from non-celibate to celibate priesthood or TLM to Pauline Mass can be called ‘disorder’. It is simply the Church exercising its right, authority, and occasionally its duty, to change disciplines, as it has often done down the centuries.
I am sorry but they are disordered. Any where that you read about the Sacraments of Initiation you will read them as Baptism, First Eucharist, and Confirmation. There is a theology behind them that is lost when you change the order.
If it isn’t disordered then why are there bishops who are saying that they are returning to the traditional ordering of them.
Maybe that is a better wording, traditional and non-traditional ordering.
But on another point.
It is the parish priests job to ensure that all those coming forward for First Eucharist are properly catechized. The OP states that he did not finish CCD but even if he had it would still be the job of the parish priest to ensure this.
Here is the relevant canon from the Code of Canon Law.
Can. 777 In a special way, the parish priest is to ensure, in accordance with the norms laid down by the diocesan Bishop, that:
1° an adequate catechesis is given for the celebration of the sacraments;
2° children are properly prepared for first confession and first holy communion, and for the sacrament of confirmation, by means of catechetical formation over an appropriate period of time;
3° children, after they have made their first holy communion, are given a richer and deeper catechetical formation;
4° as far as their condition allows, catechetical formation is given to the mentally and physically handicapped;
5° the faith of young people and of adults is strengthened, enlightened and developed by various catechetical methods and initiatives .
I know this speaks about children but one can see how this should apply to adults also.
