We use cf-xarray to interpret CF metadata in a dataset. cf-xarray can interpret different CF metadata to map to axes. For example, the Z axis can be mapped to either by axis, standard_name, long_name, positive, etc (link).
There might be cases where a dataset sets a CF attribute on an incorrect variable/coordinate. For example, in this discussion, the dataset has plev7 and tau being mapped to the Z axis. cf-xarray maps the positive attribute set on tau to the Z axis (which is probably not correct).
