I’ve tested and can confirm user with the role “Storage Account Contributor” can delete containers and blobs if for the specific storage account.
It will be easy to test from your end. Just add a new user, grant the user the role from Access Control page in your storage account. Then login as the new user and try deleting containers/blobs.
It’s best to adopt an “as-needed” approach to granting roles. If you don’t need user to manage the specific storage account, don’t user Storage Account Contributor.
