I looked at the pictures again some more, and I think on second thought what mattered more in the second picture is the flat chin line.
So I would perhaps suggest to go first for mandible contouring and only after that consider either cheek work or forehead reconstruction, and I doubt there would be a need to do both after mandible contouring. Even so, I felt like I had to try and look for masculinity in your face to spot it. If I wasn't trying hard to look for masculinity in your face I wouldn't have noticed it which is why I'm not sure you need surgery at all.
Again, as far as your nose, it has a tiny little bump, but that doesn't stop it from looking ultra feminine in my eyes. I don't think it's worth touching it. It's not thick, it has a nice upward angle. I would put nose at the level of nuance correction, much like your seemingly none existent and if it does exist it's really tiny and hidden trachea... then again if you do forehead reconstruction that might necessarily entail changing the nose to fit with the new forehead.
Regarding breasts, I'm not objective because I'm not much of a breast person. To me personally, breasts aren't what make or break being recognized as female. Lots of cis women have naturally tiny breasts. For me personally, breasts is the last priority after face is fixed, and even then I might not care, but that's just me. Then again, for me my face does not look nearly as passable as yours, whereas for you the face problems are at the level of nuance, so breast augmentation might help shift the balance so that people would never "believe" the masculine nuances even if they spotted them... whereas in my case, breast augmentation won't help at all until my face is significantly different.
Even if you want to eventually do the whole package deal, if your funds are limited now you should do what gives the biggest results first in my opinion... but since everything in your face is in the level of nuance, it's hard to say which part will give the biggest impact.
