Space Moderation is just a paid subscription feature of any paid Webex/Teams subscription. Only users on free (Consumer Org) Webex Teams don't get space moderation.
Pro Pack is an add-on to the meeting subscription, for Named User this is: A-FLEX-NU-PRO-PACK and is charged as an additional $pm per user. Pro Pack is included (I think!) with the Active User/EA buying models.
