What’s really important to you when picking an egg donor

I’m at the point where I’m ready to pick an egg donor. However, I’m finding it difficult to decide what is it that I’m actually looking for?? I know I want someone with similar physical attributes and good health, but what else? I am very proud of my Italian heritage and I’m having a hard time accepting I may have to totally give that up. I know , I get it it , won’t be my genetics anyway, but how did you all decide what really matters when making a selection?
