The problem is that not only does the fighter need to be decent at skills and is comparable to 80% of the other classes, they have to be as good or better. Heck, fighters aren't good because they can't compare to a bard who's main reason for existence is being the party's face?
It's not like every party has a bard. If there is a bard, then odds are, the fighter can focus on something else. Maybe they focus on stealth and picking locks because the party has no rogue. Maybe they focus on survival skills or use one of their extra feats to take the healer feat and help keep the party alive.
The point everyone is making is the fighter can't compete with any class for spotlight outside of combat.
So often the fighter player ends up waiting for everyone else to pick their class and specialities, then they can choose from whatever is left. Which gets worse the bigger the group.
The party has a sorcerer, artificer, rogue, and druid. Maybe they can spec to Athletics exploration?
