+1 for racial ASIs of some sort, as different races (which in D&D are essentially different species, albeit somehow able to interbreed) do have distinct inherent racial traits.
I agree that this can feel punishing using point-buy, so I wouldn't be opposed to some solution here. Maybe an increased point buy that allows you to buy a 16..? But, as has been mentioned above, rolling for stats would allow any race to get an 18 in a stat at level 1, which is more than good enough.
I could also agree that the +2/+1 is too much to be determined solely by race, and that these bonuses should be split into 2 or even 3: racial (unchangeable), background/culture (chosen), and/or class (limited selection of options: e.g., fighters can choose between str and dex; barbarians between str and con; wizards can only choose int; etc).
Also, potentially the ability score maximum of 20 could be raised based on your race. Orcs have a natural potential for a 22 strength, elves for a 22 dex, dwarves for a 22 con, gnomes for a 22 Int, etc. Though I think this change would need to come with separating ASIs and feats, otherwise it'd even more discourage taking feats at high levels. I don't think there should be racial reduced stat maximums, as a max of 18 provides very little room for improvement.
