As one of the posters says, Dwarves should have +2 to STR and CON, it makes the most sense to me. Sure, they could have sneaking, but height shouldn't be the sole factor in making a better sneaking person. I could easily see a slim, fast elf be sneakier than a bulky, slow dwarf. For elves, +2 in finesse and +2 memory seems more matching since elves can now read memories of the dead it makes most sense they have a bonus in it. As for lizards... hmmm... it really depends on the direction Larian are pushing them to be, a more magic or strength orientated race. To me, they are more magical than brute, so perhaps a mix of +1 and +2 for magic bonuses, maybe even intelligence?
Humans are humans, you could apply any bonus to them really, but the leadership and wits bonuses are fine.
