It is totally your choice, you're right
This is the info I give people on the reasons and potential benefits for a spay.
The way I looked at it when I was deciding whether or not to spay my first rabbit was how will I feel if they get an illness I could have prevented. Personally, I couldn't live with myself because I had a chance to keep a bunny healthy and didn't take that choice.
I then also thought, if I don't spay when my bunny is young/healthy then there is still an 80% chance she will need to be spayed because of the 80% risk of uterine issues. Also, knowing rabbits, by the time that she had shown problems, she would be very depleted and more unlikely to survive the operation, have a harder recovery, or, she may be too ill and need to be PTS. So therefore, given 80% is pretty high, my options were to get the bunny spayed with healthy or to wait and then get her spayed when she showed signs of illness. So, either making it easier for the bunny to recover because she was fit and well, or making it harder for her to recover because she was already ill.
When I chose to have the first girls done it was terrifying (I had two done the same day), but I did what I thought was best for them and gave them the best chance for the happiest life; neither of them could be bonded because both were grumpy hormonal madams, and now both are happily bonded, well over the age that potentially uterine cancer can develop and doing really well. I know I made the right choice. I made the same choice for all my healthy bunnies.
Equally, I've had ill bunnies come through where I've had to make the decision not to spay
at that point. I had one I expected would never be spayable but she got better and better and then was able to be spayed. I had to take the risk for her because her hormones were causing her fights with her bonded friends and she would either have to live a sad, lonely life not spayed having known bunny love, or risk an operation that could kill her to give her a chance of a happier life with friends. She was spayed 18 months ago and has never looked back.
Those are only my experiences, and the views I look from. You may decide to take a totally different viewpoint and that's ok. As long as you're doing what you think is best for her then you'll make the right choices.
