Schedule Jobs Page on Multisite
This is actually the correct interface.  I believe you're trying to compare the "List Scheduled Jobs" interface with the "Edit a single Scheduled Job" interface.  If you press "Edit" next to any scheduled job on your "main" site, it should look more or less identical to what you've posted above.

Crucially - when configuring Scheduled Jobs for multi-site, most jobs do NOT need to be run twice.  E.g. "Update Membership Status" works once across all contacts.  You DO need to replicate the "Send Mailings" scheduled job on each multi-site instance; you can copy the settings from the main site's "Send Mailings" interface.  I think you may need to change the name to something unique.

In my experience, the only site-specific scheduled jobs I create are "Send Mailings" and "Process Incoming Mail" - the latter because newly-created contacts won't be created as belonging to the correct "master group" for the domain otherwise.  IIRC even bounce processing is just done once for everyone.
