I'm seeing the same issue in a customer tenant, no modern sites w/ groups are able to be created. In fact, we're not able to do so using any of the following approaches:

- Using the modern administration portal Create Site link
We're now using this approach:

so using an AAD app identity with delegated permissions, and calling into MS Graph.
It is in general more reliable than other approaches you mentioned, and we've tried as well. Especially in regards with the associated SP modern site, which gets provisioned in a timely fashion consistently with this approach
Hope it helps
