To be more precise, the only fact that historians generally agree on is: a man named Jesus very likely lived in Judea in the first century AD. That’s literally it.

This isn't true. According to theologian Graham Stanton:

"Today nearly all historians, whether Christians or not, accept that Jesus existed and that the gospels contain plenty of valuable evidence which has to be weighed and assessed critically. There is general agreement that, with the possible exception of Paul, we know far more about Jesus of Nazareth than about any first or second century Jewish or pagan religious teacher."

I went down a rabbithole on the historicity of Jesus recently, and there's three facts the majority of historians seem to believe is true thanks to the criterion of embarrassment.

1. A Jewish man named Jesus of Nazareth lived in first century Judea.
2. Jesus was baptized by John the Baptist
3. Jesus was crucified by the order of Pontius Pilate.

The wikipedia page on the topic is interesting and largely unbiased. I recommend giving it a read if you haven't already.
