Limiting iCloud for Photos

Hi all,
As a keen photographer I’d like to have my Favourites folder available across all my devices. But am I right in believing there is no way of doing that?

I’ve look at the options, loading all my photo library to iCloud I s not an option (30,000+); even the last 30 days can sometimes be thousands of photos; and the only other option seems to be a Shared album. But can that be my Favourites album? Not that I can see.

The cynic in me thinks Apple is trying to get me to pay up for more iCloud storage. But it’s not just that, is capacity on my iDevices also I don’t want thousands of photos on.
