There is no official support for ZFS root yet.  So in most situations
you'll want root on UFS, yes.

There is no way to do that during an interactive install.  You can
specify it in a jumpstart profile, but that seems to be quite a bit
fiddlier than mirroring after installation.

You mean for the root filesystem?  I don't think that's known yet.  The
announcements about the support of root on ZFS have mentioned that they
are not targeting raidz or raidz2 as an initial option.  I certainly
wouldn't plan any current system with that in mind.
