They would not. If a goblin would only be able to reach 14 Wis then a Wood Elf would only be able to reach 15. A High Elf would also start at 14 Wis.
Do you not know how the ASIs work? 15 is the max you can put in an attribute. Wood elves get a +1, which lets them get to 16.
A goblin can get to 15, but there's no mechanical difference between 14 and 15 so you'd never do that normally aside from specific attribute boosting strategies.
So the goblin only gets a +2 to its Wis related rolls, including spell saves and the like, while the wood elf gets +3.
It isn't a huge difference but it is an average 5% higher chance to succeed at casting druid spells, which over the course of a long game can add up to a lot.
Indeed, it can add up.
So do you min max, because that 5% is unbearable, or do you RP and pick a race that does not get the exact benefit that is only about 5% better, that better fits what you want?
Do you want races to be more similar? Or less?
And what happens when some race provides no meaningful benefit to being a fighter, while Half-Orcs are over there with their purely racial benefits? Do we ask that they lose those, or do we turn them into feats so that all races have the same potential?
When does it simply become 'forget about different races'.
I think currently where we are right now post Tasha is the ideal. Races still have a lot that makes them unique and players have a 2 and a 1 they can assign freely. While a half orc has relentless endurance and savage attacks, those can apply to more than just the fighter and is something distinct to them, and while useful, doesn't make them absolutely better pick than say an Arakocra who can now be an effective strength based fighter in pointbuy and is able to fly. Races still have their differences but now there is less dependence on picking the right race to have a place at tables that emphasize combat or difficulty. Also it doesn't erase the flavor of races cause a typical member of that race will have the listed ability scores. That hasn't changed, lorewise it still exists, but most players are not playing a typical villager so being able to manipulate them is good for players to make a unique player character.
