Because the abilities are now all player-choice "lineage" design, there is no longer a reason for separate elf races.
Every elf can be one elf race, with a player choice of a level-2 spell or level 1 plus cantrip; plus swapable Darkvision (which I consider a powerful cantrip or level 1 spell).
The writeup can say members of an elf community often share from the same assemblage of typical spells and cantrips. But individuals might vary.
So, using the same race stats, a High community might tend to choose Misty Step, while a Udadrow community might choose Darkness. And so on. The mutability of potentially other spells is a known elven quality.
