I haven't given thought to SRS. I will probably want to get it eventually. The short answer to OP question is that I will be content with whatever I can get out of transition. I'll be content with whatever resources I have available, whatever treatment or surgery options are available.
Let's go with something that is clearly not available. There is no surgery available at this time that can implant us with female reproductive organs. Do I ever wish I could someday carry a baby? Yes. If hypothetically such a surgery were available, would I consider it? Yes, I'd at least consider it. Is the fact that I'm not going to be able to carry a baby, and that no such surgery exists today, going to stop me from transition? No.
Although the transition processes are still very rudimentary, we've come a long way from what we used to have. Imagine how it must have been 100 years ago for trans identified people to have no HRT, no electrolysis or laser, no surgeries, and the best they can hope for is to put on a wig or grow hair out and wear women's clothes, and have to fully accept their male bodies. And the world was far more unaccepting back then than it is today. And back then it was impossible in all states and countries to change their gender.
Yet, not all transgender people have hid in the closet, even in the day where no medical treatments were possible. Think about the Muxes in Mexico, Hijira in India, or Kathoeey in Thailand. These people have lived as women, or as two-spirited individuals, and have been doing so for centuries without any the medical treatments we have available today.
For me, personally, I'm more concerned with social integration than anything else. That's me.
