Install default, and change on the fly then conclude yourself. It will be an amazing journey.
You wouldn’t want to use standalones in Qubes (thus meaning HVM) unless it’s impossible to use distros otherwise.
This means, sys qubes with dedicated hardware have to be HVM, as well as Windows qubes (standalone or template, search the forum)
Kali template is officially provided in qubes-community-templates-testing repository, and @unman provides many other templates beside Ubuntu .
If I’d want to use only standalones, I’d reconsider using Qubes, although it is better than running them in virtualbox-like environments.
If you ask why, you can read it here why PVH is more secure than HVM
