Here is a link showing some comic book storylines highlighting the character's change from the 1970's to the present:

I am not familiar with the more recent stuff but
Thicker than Water (1986) and
The Triton Saga (1998) are both good reads. It is pretty obvious how DC were aligning their character more with Marvel's Namor the Submariner.
Flashpoint (2011) inspired
Justice League: The Flashpoint Paradox (it's on HBO Max) animated movie a few years after. It is a multiverse type story where Aquaman is flat out ruthless, like literally cold blooded.
It has taken a long time but DC has done a moderately good job reversing the joke of a character they created way back when. Aquaman needs far more visibility in the future to erase that past nonsense though.
