Perhaps your approach is wrong. “Put in work and ask for extra responsibility that will help you get a better job the next time” doesn’t mean fluffy resume padding, it means putting in effort at the next level so the bosses see that you deserve that promotion. It means gaining actual skills and experience, not some resume talking points that a tiny bit of scrutiny would reveal as fluff.
