I'm gonna say something shocking that you need to hear.
You have a male voice box. You will never sing like Maria Callas. Singing in full modal voice as a trans woman and sound cis can be done even with a decent range too but what you can sing adequately will be limited not to mention the quality/richness/power will always be questionable/ sub par. You can seek formal training as a counter-tenor but then I hope you like singing opera because that's pretty much all you'll be able to sing. You won't sound half as good as a bad cis woman too.
Be weary: You cannot "stretch" both ways. Meaning that the more quality you gain on one end of the register you lose it on the other. For a while I pushed my voice in both directions but since I live full time as a woman my male voice is not what it used to be and I lost a few lower notes. So technically it's very counterproductive to fall back on your male voice and especially sing. At some point my throat really itches when I do certain male register sounds or voices I could do effortlessly before.
You will be able to sneeze and sound 100% like a woman sneezing and you will be able to clear your throat but only partially. You cannot fully clear your throat when you have a really bad itch and still sound female it's simply not doable. However, somebody that is oblivious to the fact that you're trans might not perceive it as such though. Depending on your self-control bursts of laughter could be an issue too.
So I hope you found this informative and not too discouraging 
EDIT: Oh and BTW... Forget voice surgery. Period.
I'm going to disagree with you on quite a few points here. Everyone has a range, and everyones range can be expanded with training. Opera singers do not just suddenly pound out at a coloratura soprano... they train, expand, train, expand. Now, yes, at some point, everyone will reach their maximum ranges, and that is unique to each person. I have seen MANY trans women with low voices sing full out female, and you could never, ever tell they weren't a cis girl. I've seen and talked to voice therapists who have showed their work, with people flawlessly singing in a female range, speaking like a cis girl, and going back to their male voice flawlessly. And also, since I do voice over work in male voice, and am working with a voice therapist (Who specializes in TG women), even she said that I will be able to go back and forth to do voice over work in either gender at will.
So, if you try these things by yourself, you will get so far. If you train with a professional, you will get farther. This goes for anything. Golf lesson, learning a new trade... when you train with someone who knows what they are doing, you can get farther than doing it by yourself. Your limits are not as solid as you had in your post. I've seen it, I've heard it, and I am actually doing it myself. While your experience has been limiting, I assure you, that is not the way for everyone. You can not believe what you can accomplish with voice when you get with the right professional. (A final example is people who work out by themselves trying to get in shape... then suddenly work with a trainer and get leaner, stronger, and more cut than they ever did by themselves. they thought they were pushing to their limit by themselves, and then suddenly, with proper instruction, go farther than they ever imagined.)
