I think the key is to be consistent with user expectations. If the
user's init.el is under XDG layout, then use that, otherwise use
user-emacs-dir. This is slightly different to your No. 2, as I suspect
in the first run of org, it could be possible that init.el is under XDG
layout, but there is no org-persist yet.

Most important requirement would be that the location is a custom
variable, allowing easy customisation for those who want to set it
explicitly.
