Camelot
Adventurer
I don't remember off the top of my head which races are in the first essentials, and I'm too lazy to look it up, so I'll just guess all the PH1 ones.
Dragonborn: +2 Str, +2 Con/Cha
Dwarf: +2 Con, +2 Str/Wis (though this would be what I'd do in an initial release; you might be right about the feat things, and Int would be my second choice)
Eladrin: +2 Int, +2 Dex/Cha
Elf: +2 Dex, +2 Str/Wis
Half-Elf: +2 Cha, +2 Con/Wis
Halfling: +2 Dex, +2 Int/Cha
Human: no change
Tiefling: +2 Int, +2 Con/Cha
I also have guesses for the rest of the PH races, and I even thought about the monster races before. But we shall see!
Then I'll add:
Drow: +2 Cha, +2 Dex/Int
Half-Orc: +2 Str, +2 Con/Dex
