I think it's currently very difficult to find the Foundry VTT (and probably other VTTs) content on the site.
If I didn't know it exists from Reddit and googled for it I would not have found it at all.
Maybe there could be a dedicated category in the webshop, like "Pathfinder -> Virtual Tabletop -> Foundry VTT" where we can browse all content available for a given VTT?
I think there also were modules for other VTT software, but I couldn't remember which ones and I didn't find them anymore.
