Biologically speaking, in most mammal species males are built for quick bursts of brute strength, while females are built for endurance. Hyenas are an exception though, the females are built for brute strength and endurance, while the males are just super-submissive. It's why when working out, in general men tend to gain bulky muscle, while women tend to gain long/lean muscles.
Yeah, I think it's this tendency that often leads to "token" characters --be it token female, token racial/sexual orientaiton minority-- etc etc. I'm not one to demand that all fiction has a representative balance of genders, orientations (the whole scale of genders and orientations), racial makeup etc etc, but I think it's important that regardless of these details, characters are written as whole human beings.
Well, I agree, though like you I might be biased (but like I said, I like to think that I don't see things regarding Sakura because I want to see them, but rather because I see these things --and because as the story progresses and I've re-read and re-analyzed the story-- these aspects are the reason I like her).
Bolded: Interestingly, there is one female manga character I know that follows your example to a T (although I'm sure there are others).
Erza Scarlet. Her basic strategy revolves around herself tanking hits from her opponent until she figures out their abilities and pulls out the perfect weapon to counter them. And her physical strength is definitely very, very high (not to the point of super-strength, though). She can almost rival Gajeel in terms of tanking hits, and the latter is literally made of iron, to boot.
As for your second point, at this point, the way I see it, Sakura is nothing but a token character. Hell, even the hero himself is starting to be reduced into one. The manga should literally be renamed Sasuke at this point. Unless Kishi does something about this, my opinion's not gonna change. And I'm not talking about fights, either. I'm talking about how each character should be contributing to the plot in their own ways. Hell, even Ino is moving and contributing more to the plot than Sakura.
Don't get me wrong. I do like how Sakura's humanity is shown, but Kishi forgets that the story is set in a fantasical setting, In fact, I think Kishi has a serious misconception about her character. Kishi is too enamored with the beauty of humans' shortcomings. It's not wrong to use that as an aspect of a character, but it's getting to the point that it is stalling her development. Y'know how some people get stuck in the same job/position at a company for years?? some of the reasons include them being too comfortable in their position, simply because they don't want the responsibility, when they actually can do more.
The reasoning for Sakura to me, is similar. She's too comfortable being a medic-nin and staying at the back, when in fact she could do more. Not saying this makes her lazy, of course. Just.... why hasn't she thought of trying something else aside from the medical ninjutsu taught her? Please tell me she knows Katsuyu came from a place where you could learn Senjutsu (maybe). Because if she did, I just have to facepalm and resist the urge to call her a dumb broad. If not that, I would also question Tsunade herself. She could have at least mentioned SM in passing to her student. Knowing Sakura, she would naturally be curious. Even if Tsunade told her it would be impossible, wouldn't this have pushed her to try prove her master wrong??
If she did know, well congrats Kishi, you not only dumbed down your hero, but you also dumbed down your heroine. We all know Sakura can do more, it's just that Kishi is lazy to do something about it, which in turn, makes her look lazy.
Also, regarding the stalled development I was talking about, my point about her being too comfortable with her current self still stands. She's too comfortable with herself right now that she hasn't gotten up the gumption to talk about herself to people she cares about (her team, Tsunade, Shizune, etc.) Hell, I would dare to call her an emotionally reclusive person. Remember Yamato's advice? I get the feeling she hasn't even realized it in full. And all this because either she refuses to talk about it or something else. That's a big question mark for her character but Kishi hasn't even bothered to bring it up at all. And it feels too late in the game too, if it's brought up. Kishi had many opportunities to do it, but he didn't.
If he brings it up, I feel like it's going to end up looking more like an afterthought of her character that Kishi brought up for the sake of tying loose ends instead of actually developing her character.
