The term ‘Elf’ needs to be for a family of races, not a specific race.They also usurped the name of the Eladrin that had been in the game in 2e and 3e, which is problematic both for player confusion and in-setting continuity.
I wouldn't be averse to keeping the 4e "eladrin" in 5e, but it needs a different name altogether, especially if they're seemingly going back to the Great Wheel cosmology.
Then the ‘Sylvan’ Elf race can have high Dexterity and correspond to the classic D&D Elf archetypes. Meanwhile the ‘Celestial’ Elf race can have high Charisma and correspond to the 4e Eladrin archetypes. (Compare how ‘Dragon’ entry is a family of races that divides into ‘Metallic’ and ‘Chromatic’, even ‘Gem’ and so on.)
SYLVAN ELF
Wood Elf (Dexterity Wisdom)
High Elf (Dexterity Intelligence)
Wild Elf, ‘Grugach’ (Dexterity Strength)
CELESTIAL ELF
Sun Elf (Charisma Intelligence)
Moon Elf (Charisma Wisdom)
That said, I notice, the 2e Eladrin from the Monstrous Compendium corresponds closely to each kind of Elf.
SYLVAN ELF
Wood Elf (Dexterity Wisdom) ≈ Shiere
High Elf (Dexterity Intelligence) ≈ Ghaele
Wild Elf, Grugach (Dexterity Strength) ≈ Bralani
CELESTIAL ELF
Sun Elf (Charisma Intelligence) ≈ Tulani
Moon Elf (Charisma Wisdom) ≈ Noviere
(?) Star Elf (Charisma Strength) ≈ Firre
SPRITE
