It would be even better to stat the Elf as:
+2 Any Score
Choice of 5 Major Elf Traits
1 Default Language
(Major Trait ≈ ½Feat = +1 to Any Other Ability Score)
(2 Major Traits = 1 Elf Feat = +2 Any Other Ability Score)
(1 Major Trait = 2 Minor Traits)
(Choosing a Handicap gains 1 Minor Trait)

A DM can easily customize their own Elf culture for their setting.
