You're very, very right when it comes to body composition and things of that nature as well as skin coloration. However, the basic ingredients even there haven't changed much. Women with a narrow waist and wide hips have always been a preferred shape, some times with more fat, some times with less, because of the birthing health it signifies. Same for men with broad shoulders, narrow hips, bigger wrists, and a thicker neck.
Skin coloration preferences, actual body composition preferences, obviously style preferences, etc. have all changed dramatically as you said.
One other thing is all the factors you mentioned are overall appearance factors. My post was specifically directed at facial attractivness, which is fairly objective. When over 90% of people rate within 1 point of the mean, that to me is much more objective than subjective, and the qualities we like in faces remain the same no matter who. In the case of women: high set, forward and laterally grown cheekbones, forward grown midface, bigger eyes but with minimal eyelid exposure, no showing of the whites of the eye on the bottom, nice shape to medial canthus, horizontally longer than tall, facially no too long and narrow ("wider" face), promiment, defined jawline (but more curved and "softer"), full head of hair with a low hairline, good eyebrows, symmetry and facial harmony, etc.
Nobody finds these things unattractive. Variations on a theme yes. I.e. one guy might have a preference for women with a more masculine, angular chin whereas another might like a (still defined) softer, rounder chin. Nobody is going to find someone lacking jaw definition as defined as someone with jaw definition. Nobody is going to like someone with poor, hollowed out area under the eyes more than someone with nice, well supported eyes, etc. The good features all have to be there, different people just like different facial phenotypes.

Both guys have all the makings of a very good face I mentioned above, but these are two variations on the same theme. You can clearly see the eyes with good hooding, thick eyebrows, strong brow, very well supported eyes, forward and laterally grown cheekbones gives a nice slope an evenness from eye down to nose in the midface), good jawline with a wide face, and neck around the same size as the head.
