Depending on your proportions, some necklines might work better for movement or fit. Like, high necklines on a rectangular t-shirt, if you're well-endowed, have a tendency to creep up and get all chokey. Scoop necks do a better job of this.
Some people might consider scoop neck to be "low cut" (because the collar bones are visible--something generally not accepted/expected of men) while others might not call something "low cut" til cleavage is visible.
Now, a button-up shirt does a nice job of leaving space for your throat so you don't feel like you're choking, but in case you haven't noticed, it can be difficult these days to find button-up shirts for women that have all the buttons. It has become extremely common to manufacture women's blouses without the second button, or rather, with the second button roughly 6 inches below the first one. I suspect this is due to rules in schools and workplaces allowing for the top button to be left unbuttoned. That way, you're following the rule and showing some decolletage. I once went through every button-up blouse I could find at Target. I came away with having found one rack that had shirts with an upper-chest button. (Oh, and if you button all the buttons on one that's missing that upper-chest one, it just gapes open)
If the shirt itself is not quite wide enough to accommodate being well-endowed, a lower neckline can allow the fabric to move horizontally to better fit around the girth involved by opening up a bit wider. On the one hand, you could get a bigger size (if that's even available--there are limits), but if you've got a small waist, there's a tailoring problem for you. And if you've got shoulders that are narrow but a chest that isn't, that's a much more difficult tailoring problem.

Thank you for pointing out the nuances of female tops commonly available today and how they look on different body shapes.
With regard to button-up shirts, tailoring is a much bigger problem for women's shirt than men's shirt. Ready-made men's shirts are measured in collar size in 1/2" increments and sleeve length in 2" increments. This allow for much better fit, as men's shoulder and chest measurements tend to correlate with these two numbers.
For women's shirts, you're at the whim of the mythical "sizes" running usually in increments of 2 from 0 to 14 (larger if you're at the "plus" section). Each size up is usually scaled up at all measurements: chest, shoulder, waist, collar, shirt length and sleeve length.
In other words, even though there's a much wider variety in women's body shapes than in men's, men's shirts' come in much finer increments in terms of sizing.
In addition to the problems you've describe, I have a few more gripes regarding button-up shirts:
There's the problem of large gaps opening up in between buttons for the well-endowed, thus offering others glimpses of your undergarment (read: bra). Opting for a larger size would make the shirt too loose ("not fit") at the shoulders.
Another common problem with button-up shirts for women is, they tend to run much shorter than men's shirts, as they are intended to be worn not tugged in. Depending on body shape and the cut of the bottom garment, certain movements (such as raising the entire arm) may expose skin along and possible above the waistline.
Unfortunately, button-up shirts are part of the de facto business casual attire. Depending on the physical environment, adding a vest, cardigan, or jacket for cover-up may not be suitable or desirable. (Female jackets tend to hang above the hip bones anyway, so they're not offering much help in the regard of protecting skin from being exposed.)
In other words, no, I don't want to expose my skin or cleavage in the office, but sometimes it's unavoidable.
Some people might consider scoop neck to be "low cut" (because the collar bones are visible--something generally not accepted/expected of men) while others might not call something "low cut" til cleavage is visible.
