I wouldn't use the word "judged," which to me implies conscious deliberation. I mean, sure, there are some people that judge by looks, but I they're actually in a distinct minority. But I think most if not all people automatically and subconsciously respond to how someone looks, because this is how our brains work. We can pretty much instantly tell if someone is a man or a woman, just like we can instantly distinguish cats from dogs. It isn't a matter of "judgment."
So the first thing to consider, from a practical standpoint, is whether it's needed in order to consistently and unequivocally elicit female gendering. It isn't always necessary, but for the majority of us I think it is. Second, then, is whether to go for a minimal approach or a maximal approach. And again, that depends -- there are resources to consider, primarily, both financial and in terms of one's health. I myself think a maximal approach yields the best results -- for there will be physiological limits regardless, like the position of the mandibular canal from which the mental nerve emerges, which limits how far you can go with jaw surgery. There's the length of one's midface (the vertical distance from the center of your eyes to the center of your mouth) which makes certain proportions of the jaw and hairline distances look, well, proportional or not.
Of course, there are all kinds of women out there, women with long chins and long upper lips and faint brow bossing and the like. But our brains process images by gestalt -- the sum total of all features, and if too many features correspond to the maps we have of "man" instead of "woman" then misgendering will occur. Now, if you're fairly immune to social dysphoria this won't be a problem, but then you probably wouldn't be considering facial surgery in the first place, and by extension your priorities in transition will be completely different.
I don't think we have a choice in how we experience the complex set of emotions we call dysphoria, and emotions begin in the subconscious, before conscious thought. While philosophical considerations are all nice and good, when it comes to our lived experiences it's going to be our emotions, one way or another, that determine what we're really going to go for.
