The documentation says, "The
wid claim represents the tenant-wide roles assigned to the user from the roles present in the Azure AD built-in roles."
Based on the claims validation guide, the directory role template object IDs should only populate within the wids claim for built-in/directory roles. The role to template ID mapping is documented here.
You mentioned that you created a custom role and add the templateId optional parameter. Based on my understanding and what is stated in the documentation, I do not believe that the wid claim from the custom role templateId should populate. (I did send a note though to the product team to confirm that the documentation is up-to-date, and will update this post if I hear otherwise.)
When you create a work account in Azure AD without granting any roles, the
b79fbf4d-3ef9-4689-8143-76b194e85509 id will be populated into the
wids claim. This exists in all non-guest accounts of the tenant.
