Need help naming a character - which name fits him better?

I've got a character that I can't quite pin a first name on. I'm down to two options, which are close in popularity for the character's birth year. (The names were not very popular, but were both used over two hundred times. One was a tad more popular than the other)

The character in question is an American-born male, in his mid-thirties. He has light brown hair, hazel eyes, and nearly unnoticeable freckles. Slightly brawny in frame. (Think a somewhat more athletic Richard Speight Jr)

In personality, he is a bit of an eccentric. Nameless Guy works for a natural foods company, as a buyer. He's good at reading people, not the most intelligent guy around, but he knows how to use the wit he's got quite well. Sarcasm is familiar territory for Nameless Guy, he doesn't take many things seriously. Had a decent upbringing, and only child to Catholic parents, and rocky teenage years that he masks the memories of with humor. Basically, he's kind of an arrogant d-ck who will become a better person later on, if a bit too late.

The names I am considering for him are Elias and Avery. (Avery is not a girl's name. It is unisex and wasn't popular for girls until quite recently) Surname is Cooper.

Thank you in advance to those who answer! (And sorry for posting in Baby Names! Books & Authors seems a bit dead right now, though)
