Depending on what exactly you need. If you rather want to work in the cloud (i.e. OneDrive), I would recommend an Office 365 subscription, which has to be paid annually (
Microsoft 365 Single (1 y., 1 x, Windows, macOS, iOS, Android, Italian, French, English, German).)
If you prefer to pay for Office only once, Office 2021 will suffice (
Microsoft Office Home & Student 2021 (Unlimited, 1 x, Windows, macOS, German).) Of course, there are advantages and disadvantages to both choices, which I will be happy to discuss if necessary.
