There were meaningful competing theologies, there were not meaningfully different competing narratives of the historical events.
Of course, they all agree on a broad narrative - Jesus was born of a virgin Mother in Bethlehem, lived in Nazareth for some time, wandered for 40 days in the wild where he was tempted, then returned and was baptized by John the Baptist, collected a number of disciples while preaching in Galilee and performing various miracles, then during Passover entered Jerusalem, came into conflict with the Jewish religious authorities and/or the Roman authorities, had a last supper with his disciples, and was crucified, died, was buried in a tomb, and was resurrected.
This is about it in terms of the major plot points that are common. Major acts, such as expelling the money lenders from the Temple or the resurrection of Lazarus, are not part of the shared narrative - they either occur at different times (in John, expelling the money lenders is one of the first acts of Jesus, at the start of his ministry, not one of his last public acts at the end), or not at all (the story of Lazarus is only present in John).
I would say that there are indeed major narrative differences between the Gospels.
Then you have all the ancient texts here https://en.wikipedia.org/wiki/Gospel#Non-canonical_(apocryph... which were likely written very early and often conflict quite strongly with then New Testament narratives. We can assume that this is just an only very small sample of all the stories floating around.
Even the official gospels don't all match on all the details despite retelling the same story (https://en.wikipedia.org/wiki/Q_source) since they are all included that would indicate a few hundred years later nobody really knew which story was true or not.
They were not likely written very early in almost all of those cases (your own link dates every single one to well after the canonical gospels), and almost none of them have meaningful narrative differences (once again, as opposed to theological differences.)

The canonical gospels were all likely written within decades, not "hundreds of years"; and while you can argue canonization did not officially happen until much later, de facto canonization occurred very, very early. The others floated around, yes, but they were never mainstream in any sense.
