(He, Him)
Something to think about is whether all of the +1 (Half ASI) feats shouldn't be to any ability score? My first-pass thinking was that there should be essentially four categoriesHonestly, the more I think about it, the more I like the +1 of your choice. What harm would it bring? You are still only getting a +1, and it will support a wider range of builds an concepts. Both the superstitious Barbarian that wants to smash all wizards, and the sly bard who eats casters for breakfast.
1) Full ASI feats - no stat bump
2) Half ASI martial feats - stat bump to physical stats (Str, Dex, Con)
3) Half ASI caster feats - stat bump to mental stats (Int, Wis, Cha)
4) Basic feats - stat bump to any stat
That lets us make the basic feats a bit easier to take than the others, because whatever stat you want bumped you can attack a basic feat to it. Martial feats become less likely to appear on casters, because you have to want a physical stat increase. Caster feats become less likely to appear on martials, because you have to want a mental stat increase. Of course, the classes are not so neatly divided. A Bard or Paladin might want to fix an odd Charisma score. A Cleric or Druid might be looking for some Constitution. I think that's why Resilient in my survey is the second most picked feat! So should it be just two classes of feat
1) Full ASI feats - no stat bump
2) Half ASI and Basic feats - bump to any stat
