Need ability to sort, filter, search Hubs and associated sites - any/all operations relating to a Hub and their associated sites.

For instance, in "Explorer" tab a top-right filter should be "Hub Site", and when selected, it only shows Hub sites in the list, upon clicking, a select hub site, you can then navigate the various sites in the hub - assuming you have access.

Similar for reporting, you should be able to specify a hub and navigate through it.
