Saddle discomfort during very long rides is one of my strong motivations to train standing to pedal. I used to rarely get off the saddle during a 7 hour no stop ride and consequently, my butt starts to hurt.
I stand a lot, have bad feet which require orthotics, and I don't find much of anything you wrote to be true for me. I suspect there's a lot of variables in feet and body size, etc., that are going to affect the best fit of footwear to the task of riding out of the saddle for any individual rider.
