Seems like in an interactive cluster it will set the host correctly and get a bearer token all transparently as expected. For some reason the host is not set when running the same notebook in a job cluster, causing all attempts to use the WorkspaceClient with the host set to https://none/. Same user for both the interactive and job clusters and both running 12.2LTS.

I've also tried directly setting host=https:... in the WorkspaceClient() initialisation but the runtime auth seems to ignore that.
