How about:

  if (credential_type == CredentialType::CREDENTIAL_TYPE_EMPTY) {
    ui_controller_->ChooseCredential(autofill::PasswordForm(), credential_type);
    return;
  }

  DCHECK((credential_type == CredentialType::CREDENTIAL_TYPE_LOCAL) ||
      (credential_type == CredentialType::CREDENTIAL_TYPE_FEDERATED));
  ...

This is basically the same length but is less indented and hopefully slightly
easier to parse.

Done.

+  if (credential_type == CredentialType::CREDENTIAL_TYPE_EMPTY) {
+    ui_controller_->ChooseCredential(autofill::PasswordForm(), credential_type);
+  } else {
+   auto& credentials_forms =
+        (credential_type == CredentialType::CREDENTIAL_TYPE_LOCAL)
+            ? ui_controller_->local_credentials_forms()
+            : ui_controller_->federated_credentials_forms();
+    if (credential_index < credentials_forms.size()) {
+      ui_controller_->ChooseCredential(*credentials_forms[credential_index],
+                                       credential_type);
+    }
+  }
