Honestly if the main issue is racial integrity and identity then I feel like amping up racial abilities would fix that. Who really thinks about their stats in racial terms after character creation? Racial special abilities are things that you consciously use more often and actually can stand out. Much like what Sansang2 has said. In fact that's another way PF2e does better. There are whole bunches of racial feats you get, picking one at character creation then every handful of levels afterwards. Those make races feel unique far more effectively than some flat numbers.

Also, welcome to the forum Sansang2! I hope this isn't the last we see of you!
