As I understand it many of the common potential use cases only work if you have a donor who isn’t yourself. Because if you have a genetic disease that disease will be present in your stem cells. The most common example I’ve heard is of storing stem cells to help a potential future sibling, not the baby directly. Or am I mistaken?

It has been used for the baby themselves & siblings :)

I understand that it happens, my question is the prevalence. When I looked into banking cord blood I found a lot of ‘possible’ and one-off cases, but no actual statistics about how likely it was to be useful. That made it unpalatable, especially compared to the known benefits of delayed clamping.
