The default zone and zonegroup are part of the realm so without a
realm you cannot set them as defaults.
This means you have to specifiy --rgw-zonegroup=default and --rgw-zone=default
I am guessing our documentation needs updating :(
I think we can improve our behavior and make those command works
without a realm , i.e return the default zonegroup and zone. I will
open a tracker issue for that.

It is the default behavior, there is no default realm.

Yes You can create a realm and add the zonegroup to it.
Don't forgot to do "radosgw-admin period update --commit" to commit the changes.

I just updated this section in this pr: https://github.com/ceph/ceph/pull/18063
