Because I'm not familiar with windows as a server and robocopy, and I
see it difficult to use it afterwards for backups.
Also, I have some scripts currently running on the samba server to
create directories with a specified set of permissions. Once the share
is on the filer, I could use cifsmount, but then I'll have the same
problem with permissions that I have now.
OTOH if I use unix security on the filer, I can nfs mount the filer with
no need to modify the scripts.
Anyway, if I use robocopy, with which credentials should I connect the
existing shares in order to have access to every file?

but samba can use it to show ACLs on the windows side. Even with only
the basic permissions samba does a good job in showing the permissions
under windows. Netapp OTOH....

Nope, I tried it and it doesn't work (and it is documented that it isn't
supposed to work).
You can only manipulate permissions via nfs (be it v3 or v4) if the
security is unix.
After many years of using samba I find this limitation shocking to say
the least.

Actually most of the access control is based on unix permissions, only a
handful of directories have ACLs, so I think I could live with unix
style security on the filer, but I fear that it will cause me another
set of problems in the future.
