If I may: a good name is good. a name that combines well with the surname is great. Think of Star Wars names: they are great because they mate good names and surnames. Han Solo Boba Fett Cassian Andor etc...
That said, my personal preference is something REALLY old, like Sargon, first ruler of Akkadian Empire, 2400BC. Bonus He/she/they could have also their own personal cuneiform name tattoo: π¬ππ. Now tell me that's not cool.
good hunting.
