You're basically talking about Captain America in the MCU. That's what's so frustrating about this Superman bullshyt, is that Marvel has shown that it's possible to make a character like that work in modern times.
People used to shyt on Captain America for the same reasons they shyt on Superman..."He's bland, he's boring, he's too perfect". The biggest differences between Cap and Superman is that Superman is MUCH more powerful and Clark isn't quite as stubborn as Steve.
edit:
And note that none of the Captain America Movies are excessively dark, lack humor, or try to constantly reinvent or deconstruct the character. They allow Cap to be Cap and build compelling stories around him.
