Superman and Batman origins as of current 2026 main runs

I’m currently getting back into comics, I used to be a Marvel guy but this time I’m focusing on DC. I’m currently subscribed to Matt Fraction’s Batman and I’m a little confused about where things are in the universe.

There have been so many different universe resetting events that I don’t know what’s what anymore.

What is the current as of 2026, definitive Batman origin? Is Year One completely retconned? Was it retconned but retconned back into canon?

What is the current as of 2026, definitive Superman origin? Man of Steel, Birthright, Secret Origin or a mix of all 3?
