I do think Ridley is a cute gender-neutral non-binary name, but I think this could work better on a boy. The spelling just doesn't work right on a girl.
"Good RIDdance, get RID of this name." I really like it, but a person with this name could be made fun of in that way. This is a boy's name in my opinion.
Ridley is also the name of a dragon-like alien in Nintendo's Metroid series in which he and another boss named Kraid are two gargantuan leaders of a space pirate group that the focalcharacter Samus Aran must destroy before reaching the Motherbrain. In the Metroid Prime trilogy, Ridley was revived with a metal coating, thus being renamed as "Meta-Ridley".
