We should also call out that the data will be removed in the menu option, eg:

"Delete site and associated data"

We should also call out that the data will be removed in the menu option, eg:

"Delete site and associated data"

isn't the menu label too long? everything is described in the confirmation dialog and an additional option "Delete submissions" will be added in the near future (see image).

another possibility is to have "Delete site and data" or "Delete site and submissions", but they are super long as well.

wdyt? @gino-m @jo-spek @vittorino

Then I would go with "Delete site"
