So, Fusion has different levels of Functionality, and they pair up with different levels of accounts. There's the free "Personal" version, Commercial, Start-Up, Student. Each one of them have access to most core tools, while the Personal does have some limitations (active documents, some CAM limitations).

There's the Design Extension, Manufacture Extension, etc. You can see a list by clicking on the little "plug" icon in the top right:
