I am sorry to hear about the fungal pneumonia, but glad to hear that you are recovering. I faced that one about 5 years ago and spent 7 days in the hospital recovering. It is pretty brutal.
I did not have a cord blood transplant but have met several people who have and did pretty well through the procedure and following periods. The immune suppression and conditioning regimens are a little different There are a couple of advantages of the cord blood transplant in that the cord blood is a little more flexible, tends to have lower rates of gvhd which is also more responsive to treatment, and mismatches aren't as important. Cord blood may also be faster to obtain as it does not require any scheduling with the donor.
There are of course downsides to cord blood transplants. Here is a link to a comparison page:

Good luck moving forward into transplant.
