The thing about D&D 5e is that your character isn't really built until they hit third level and doesn't come into their stride until 4th; a 4th level character gives you about the right amount of customisation options to make sure that character can succeed at the things you want them to be able to succeed at. Additionally, most people I've played with would agree that the point buy method produces characters that are a little too weak at what they're supposed to be good at to be fun. Having a max of 15 in abilties before modifiers is a little too low for a character to be focused around that ability. I think most people would like to roll their abilities so that they can get a good 17 or 18. But, 5e isn't the same as, say 3.5e when the abilities you rolled basically determined what type of class you could play, or 2e which was all over the place and even more restrictive. Like pointlessly restrictive.

Anyway you get to 3rd really quickly in BG3 which is good.
