Should I install the 32-bit or 64-bit version of Office/Outlook?

I’ve just installed Windows 10 on my computer and I’m now about to install Office. It offers to install the 32-bit version but I know there is also a 64-bit version available.

I seem to recall that Microsoft used to recommend to install the 32-bit version, even on a 64-bit version of Windows but that was some years ago.
