I think we are on the same page.
Peter preached the first gospel sermon on Pentecost.
However, all the apostles preached the identical sermon in other languages; Peter’s sermon is the one recorded in scripture.
He was the first to preach to Gentiles, specifically, Cornelius, the centurion.
He and John went to Samaria to lay hands on some Christians. It is there that he has a conversation with Simon, the Sorcerer.
Peter had some problems. He denied the Lord. He sided with the Judaizers, for which Paul withstood him to his face.
In his letters, Peter shows a depth of faith, kindness and caring that was not as evident in his earlier ministries.
At the Jerusalem conference, James, the brother of Jesus, is the leader; Peter is just a witness, testifying to his work with Cornelius.
Peter, however, was not the one on which Jesus built his church.

Sounds like it.
I have had long arguments with people before only to find out we were both confused about the other...and were arguing the same side of a topic.
Either we both lost the argument...or we both won.;-)
