Classical Ethernet uses CSMA for detecting traffic. Modern Ethernet uses full-duplex mode which does not have any collision and so CSMA/CD is not required.

Reference: https://networkencyclopedia.com/full-duplex-ethernet

Token-passing (token-ring and token-bus) were alternatives to Ethernet but did not become popular.
