In Tibet, people were not too happy about the military presence on the streets, the cultural assimilation or the mao statue in the shadow of Potala palace, but on balance are were happy to be part of China due to the economic development. People felt they would be unemployed without han presence.
In Hong Kong, the most common thing I heard was vaguely racist grumblings about mainlanders. People were unhappy with mainlanders behaving in an "uncivil" manner. There was a majority acknowledgement of China's sovereignty over Hong Kong, and a strong "Chinese" identity.
In Taiwan, things did fit your narrative pretty closely. People want nothing to do with the CCP, and many even wanting nothing to do with the mainland at all.
