This sounds more a product of censorship rather than China being particularly better in those aspects. Police in China are less likely to kill you because guns are uncommon, but they are just as shady if not more, especially in more remote areas. Healthcare access and affordability are also worse than what you'd expect from a communist country. Homelessness in China is definitely a lot worse than what state numbers suggest. They just drive out homeless people who they're less visible.
Xinjiang is an exception; it is heavily publicly surveilled.
Internet censorship is strong. The public still has sway over government policy. When search terms are blocked, the public continues with euphemisms. The government is responsive to public opinion. The government does promote influencers with opinions favorable with CCP goals.
Chinese foreign policy is more dovish than public opinion, especially regarding Taiwan.
Dovish as in it will be annexed in the next decade and not next week?
Compared with the United States, public health care is less available in China. Retirement pensions are an order of magnitude lower (even with PPP adjustment), hence their world-leading savings rate. Social mobility is lower: getting a permit to access social services such as schools in a new city is difficult. Youth unemployment was above 25% the last time it was published; it is no longer disclosed.
Rule of law is much less strong. Injustices committed by government officials towards citizens are unlikely to be addressed.
Housing costs to income ratios are an order of magnitude worse in cities with job opportunities.
The Chinese government has chosen to allocate capital toward industrial output at the expense of its citizens' welfare. It has succeeded at its goal. Perhaps in the future more capital allocation will be made to consumption. That is not the case at the current time.
