We use a variety of devices (Win, Chrome, iOS and even Android thanks to the covid machines we got) , however for us Office worked best on laptops. As you are not going down the Apple or Chromebooks route, your costs maybe higher, depending on the spec you choose, however we got round this by using ClassLink as a middle wear solution. Teachers, students and other staff can access Office, One Drive, Sharepoint etc from this on any device.
This may not be what you are looking for, however from a cost perspective it saved us a shed load of money as we could buy lower spec laptops.
