Should I do terraform init -migrate-state here? I'm not sure what this is about.

ah, look for hidden files in your current directory
you most likely do not want -migrate-state
this usually means terraform is not looking for state files where it should - which is on GCS remotely, but locally.

Ah
I moved away my found .terraform folder, and did (from terraform/gcp): terraform init -backend-config=backends/default-backend.hcl

This resolved the situation, but I don't understand the details here. What caused this? Had I made changes to terraform state that wasn't captured by the remote state or similar?

Most likely not, as terraform prints out this error precisely to prevent that from happening.

I just ran into this again because I upgraded my terraform version.
