Each sacrament has its own designated minister. The ordinary minister of Baptism is a priest or deacon or bishop. The extraordinary minister of Baptism, in case of necessity, is anyone.
The ordinary minister of Confirmation is a Bishop, but a priest can be delegated to administer the sacrament.
The ordinary minister of Matrimony is the bride and groom, who confer the sacrament on each other. There is no extraordinary minister.
This is the case of the Latin Rite of the Catholic Church. In the Eastern Churches in full communion with Rome, the minister of the sacrament is the bishop or priest who “crowns the bridegroom and the bride as a sign of the marriage covenant”.
1623 In the Latin Church, it is ordinarily understood that the spouses, as ministers of Christ’s grace, mutually confer upon each other the sacrament of Matrimony by expressing their consent before the Church. In the Eastern liturgies the minister of this sacrament (which is called “Crowning”) is the priest or bishop who, after receiving the mutual consent of the spouses, successively crowns the bridegroom and the bride as a sign of the marriage covenant.
John the Baptists baptized Jesus. He was not an Apostle.
Only the Apostles were told to “do this in memory of me” at the Last Supper.
In the Eucharist the priest is acting “in persona Christe” Meaning that he is acting in the very person of Christ. His Holy Orders give him this sacramental grace to act in this way and really and truly bring about through his words and prayers the real presence of Christ in the Eucharist.
This is something far different than baptism.
In baptism, God washes us of our sin by our faith and obedience to him in participating in that sacrament. As such, there is no need for a priest to act in persona Criste.
For formalities and practicalities, and to protect the integrity of the sacrament the church has imposed rules that deacons or priests should perform baptisms, but baptism is not conditional to it being performed by a priest or deacon.
The Eucharist on the other hand is conditional on a priest as this is how Jesus instituted it and how he works with us.
Letting alone the latter part of your post, Jesus’ Baptism was not sacramental, nor anyone’s who were baptized by John the Baptist.
This washing of ours sins is but one effect of three meanings of baptism, which we do not give the sacrament full credit when we see only one of the meanings.
Baptism recalls deadly flood—baptism as a participation in the death and burial of Jesus (Rom 6:3–4; CCC 1227); speaks of cleansing—by “the washing of regeneration” (CCC 1215); and equally important life, whereas baptism is our resurrection with Christ to new life (CCC 1214).
Peace and all good!
The sacrament of baptism is the universal entrance into the Christian faith and is interchangeable between the Catholic Church and many other Christian communities. For example, People baptized Lutheran should not be baptized again as Catholics if they choose to switch to the Catholic Church. The Eucharist in the Catholic Church is not the same bread that is offered in other Christian communities when they celebrate the Lord’s Supper. Catholic theology requires an ordained male priest - according to apostolic succession - to offer the sacrifice of the mass which brings about transubstantiation. This is one of the four marks of the Catholic Church - it is apostolic. However, lay people can bring the Eucharist to others as Extra ordinary ministers of Holy Communion. They simply cannot offer the mass in the same way that the priest does.
