This isn't strictly a Pathfinder thing but I like this community.
Basically, there is this meme that Human Figher is a "boring" default choice or sign of an uncreative character. I disagree. Picking out a weird ancestry is not creative. Choosing a human fighter basically means that you get zero flavor from your ancestry and class - so you are forced to get creative yourself. You are forced to give your character a personality, and you are forced to solve problems creatively.
For me, the stereotype is the opposite - if a player chooses an esoteric ancestry and class combo, I worry that their characters whole personality is just their ancestry.
Of course both humans and other ancestries make for great characters if done right.
John Baldursgate sounds like a brilliant concept for a BG3 PC. Honestly I love BG3 but by far my biggest gripe with it is how boring the player character is. They even built in a solution for this problem with DUrge, but that only enables you to play an edgelord. And if you play any of the main characters yourself, you miss out on their voice acting and character development.
