I mean, if we’re going to make that comparison, China today looks much more like pre-war Germany and Japan— set on expansion. That’s pretty clearly what the anti-China crowd is worried about. Tibet, Taiwan, Philippine islands, ever expanding naval bases, aggressive displays of power around Australia, prison camps and sterilization programs, and so forth.

How does it compare to the last 50-70 years of US actions? Even if all narratives are true and significant, China could still massively benefit the world same way US did despite its vast shortcomings.

China has never had expansionist ambitions. On the contrary, modern Chinese foreign policy is explicitly grounded in non-interventionism and respect for sovereignty (the Five Principles of Peaceful Coexistence). Xinjiang, Tibet and, per Beijing, Taiwan, are internal matters. The "Philippine islands" have been claimed by multiple states long before the PRC existed.
