Great list, and I'm trying to perfect my fundamentals too by watching these masculine figures and paying attention to body language details.
What I do is I focus on one character for like 3-4 weeks and try to embody as much of his persona/body language and obviously customise it and make it my own brand.
I owe most of my fundamentals game rn to watching Jon Hamm's Don Draper on MM, I think his fundamentals are out-of-this-world. In particular whenever I talk to women and try to steer the vibe to a naughtier direction I try to emulate
this look, still gotta perfect it though. Also going to add in a few more influences, I've watched Gary Cooper in High Noon and boy was I impressed!
I might actually start a fundamentals log soon; it's something I really wanna get down by the end of next year.
