You can get zero-depth vaginoplasty. Looks like a vagina, pees like a vagina, but there's no vaginal cavity. One of the first bottom surgery for femme types I watched was a non-binary person who got zero-depth! You can also get penis preserving bottom surgery if you want. There's a whole world of options~ ☆ I think if you want you can also just have nothing? Like just your ureter has a little hole, otherwise smooth (maybe some scars).

If you want help figuring it out - imagine you get in a car crash and you wake up to a doctor saying "sorry about your genitals, we couldn't figure out how to reconstruct down there without your input - which one would you like?" And the doctor holds up a picture of a standard penis, a standard vagina, a penis preserving vagina, and just smooth. They can do whichever you want, no issues, they have all the donor tissue you need and there are, somehow, no other complications from the car crash. Literally just have to pick. The point here is to take away all the feelings of risk and the feeling that you're making an active choice of going bottom surgery route vs passive choice of doing nothing - now no matter what you pick you'll have a better idea of what you really want. Even if that turns out to be you'd rather not go through the trouble, that's fine!
