This is really my issue with the fighter. They aren't good enough at combat to justify never being capable of being very very good at non-combat challenges.You won't be as persuasive as a bard or sorcerer who can prioritize charisma but you'll be decent.
Recent feats like Skilled Expert help, by allowing you to get expertise and an extra skill, but seriously you could give fighters the ability to turn an ability check failure into a success twice a day and it'd be fine. Or find a way for fighters to "push harder" by spending hit dice to add to rolls, or give them an ability to help multiple characters when making a group skill check with a skill they're proficient in, or just bloody something that does the same sort of "just do better" thing like they have for combat, outside of combat.
Maybe a few fighting styles that incentivise strong mental stats with thematically appropriate benefits. IDK.
It's just that the argument is always that "you can't be excellent at everything" and....it falls flat. The Fighter is not powerful enough in combat to justify having next to nothing anywhere else.
