If you don't need or want the tablet form factor, go for a Surface Laptop. They're also a little cheaper and slightly bigger than the same spec in the Surface Pro.

The Surface Books are the pricey, high-end versions (the detachable keyboard is a *dock*).

The Surface Go range is the opposite: they used to be ARM processors but the newest range use Intel's entry-level CPUs. They're also limited to the Windows Store unless you pay for a Windows upgrade.
