Heck, a lot of people go through life with names they don't love but don't change it. Pick something you like, but I don't think there is One Best Name. New parents go through this all the time trying to pick a name for their kid. In the end, the name usually seems to fit the kid.
I find my name shortened to a nickname I'm not overly fond of, but it's no worse than my F name, and it's not a big deal. For me it was more important to stick close to my birth name and initials.
Once it's done, don't think about it again.
