So it is offensive for the game to say that in this fictional world such prejudices are actually correct and justified.
They are tropes, so lets break this down.
Acolyte - Int, Wisdom, Charisma - Makes perfect sense.
Artisan - Str, Dex, Int - Str is pretty weak here, but Dex/Int are fine.
Charlatan - Dex, Con, Cha - Sure.
Criminal - Dex, Con, Int - Sure.
Entertainer - Str, Dex, Cha - Sure.
Farmer - Str, Con, Wis - Absolutely.
Guard - Str, Int, Wis - ? Int and Wisdom seem weird but I guess to split off from Soldier.
Guide - Dex, Con, Wis - Sure.
Hermit - Con, Wis, Cha - Fine.
Merchant - Con, Int, Cha - Fine.
Noble - Str (?), Int, Cha - Int and Cha make sense. Str seems arbitrary but if we wanted to really think about it, Nobles have the time, and capacity to work at anything, while others have to you know, work to survive.
Sage - Con, Int, Wis - Sure.
Sailor - Str, Dex, Wis - Sure.
Scribe - Dex, Int, Wis - Sure.
Soldier - Str, Dex, Con - Yep.
Wayfarer - Dex, Wis, Cha - Yep.
This is not 'classism' at all. This is your pre-adventurer Occupation. You improve, based on what you do.
I have worked manual labour, and guess what? My muscles grew stronger. As anyone in a labour position if they have worked with a man who was a lifer, and ask them about their 'old man strength'. This is a thing.
Frankly, Noble should be overpowered and have granted every option, because its Nobles who can 'train for fun' in whatever they want.
This isnt classism, this is your character having improved in some aspects of their development related to the basic tropes of their prior occupation, which is exactly how the real world works.
