Hi and welcome to the forums!
I think it depends as mentioned, any budgie has the capability to bond well with their "human". I know that many resources online say that females are more aggressive/hormonal, and they can be, but know that it isn't guaranteed that any female budgie is going to start randomly laying eggs. Trust me, that definitely is not as common as people make it seem.
Hand-fed birds are easier to bond with, and if they are from a good and reputable breeder, are usually bred for temperament so you know that you're getting a stable budgie. If possible, you should avoid big-box pet stores as their birds usually come out of bird mills.
It depends on the personality of each individual bird. My little girl is a single lady and she's going to be three this year, she's been absolutely lovely, very bonded to me, doesn't lay any eggs, isn't constantly in a mood swing. It just depends
I wish you luck on finding the perfect little companion, it's great that you're doing your research first! Keep us updated!
