Even Android/ARM is going to use 64bit as a standard... so I would use everywhere (desktop/notebook/server/hypervisor/virtual guest) 64bit arch, except for ultra-small systems, as a small virtual server with 512Mb or Raspberry/embedded systems or very old system <1Gb of Ram. In many new systems, like new netbooks/chromebooks (even with 2Gb of ram) it's almost impossible to install the 32bit arch due to many EFI/UEFI troubles. So, except very few cases, 64 bit to me is the standard choice for every case. In your specific case, it' s a modern architecture, I would certainly use 64bit flavour.
