In addition to the products for which you want to receive updates via WSUS, you also have to choose which types of updates you want to subscribe to. However, the classifications don't reflect Microsoft's actual servicing model for Windows. Therefore, in many cases, it's not obvious why certain updates appear in a specific category.

The Unified Update Platform (UUP) reduces the size of feature and quality updates, as well as the number of reboots. It also retains Features on Demand (FoDs). WSUS and SCCM users will soon be able to enjoy UUP. For WSUS to obtain future Windows 11 updates, the servers have to be prepared accordingly.
