Those films also used those influences, but the subject was about the MCU's influence on the DCEU. They are yet the DCEU followed the MCU's lead after Snyder left.
They are, this isn't to say the films didn't do their own thing in other scenes or have other sources. I didn't cherry pick, I used a large swath from those movies that they in common with the MCU and its numerous. It's ridiculous how far people are going to deny the MCU has any influence on the DCEU.All the elements you mention can be found in some of the MCU movies, but they can also be found in lots of other movies.
I'd recommend that you look into the stuff that ties the MCU movies together in the way they are crafted, and not cherrypick examples based on that movie X outside of the MCU is similar to movie Y inside the MCU, because you're missing out on the entire history of movies.
