I am wary of proclaiming "judgment" as you say, as I hate the possibility of hurting someone's feelings, but I like to think that a little honesty is a nicer thing to extend, even if its positive aspects are hard to see at first...
With that disclaimer said, here goes... based on that photo alone:
You said you wanted to do your jaw and chin. FFS for the chin might be necessary (possibly "just" helpful), but I'm not sure if the jaw is something that will end up being a problem, once HRT has reduced the masseter muscle.
The nose is a bit unclear. It doesn't look like it needs (or could use) fixing from this angle, however a profile would be helpful in seeing if it needs to be done or not. I'm not sure where scar you're talking about is.
Brow bossing is hard to call with a frontal shot. It looks like it would be a good candidate for FFS though, from what I can see. Or perhaps the main contributor is a concave nose bridge... which would make brow bossing seem like more than it is in a frontal shot.
Forehead could be fixed with a scalp advance... and if you think you are missing hair, transplants might be nice. I don't believe these fall under the necessary category, however, as I know women (my mom in particular) with foreheads as big as or bigger than yours. Additionally, a good hairstyle will conceal the perceived flaws in that area as well.
You may or may not want cheek implants to help round the face out a bit... but this is more of a potential want, as opposed to a need.
And that's about it... I wasn't holding back or trying to be nice. But just the same, I wasn't trying to be unnecessarily mean; just my undistilled thoughts. Many things you might want to do for FFS fall under the category of a "want" as opposed to a "need" - where a "need" is something that absolutely must be done to pass, and where a "want" would be anywhere from merely enhancing your beauty, to improving your pass rate (though to a lesser degree relative to the "needs").
A lot of things besides FFS provide really solid contributions to passability. That is, hairstyle, makeup, clothing, accessories/jewellery, facial expression, mannerisms, voice, vocal mannerisms, frame, height, and weight. I'd like to ask how you are doing in regards to these things! The most important of them is your voice, but aside from the last three, they are all very important things to be adept at. And, of course, HRT helps as well...
I can't say for sure which surgieries will or won't be necessary to your passability... It's possible that the above could do the trick by themselves. I would address them before worrying about FFS, else you'll end up having to do a lot of reconsiderations...
Hope that was at least a little helpful. I'd really want to see something other than your worst photo though!
