So have most of us. But probably by now it should be clear that no
technology can provide concrete recommendations. They can only provide what
might be helpful which varies from env to env. That's why I suggest look at
the comments in cassandra.yaml and see which are applicable in your
scenario. I learn something new everytime I read it.

BTW: Can you be clear as to what kind of recommendations are you referring
to? NetworkToplogy, how many copies to store, uptime, load balancing,
request routing when on DC is down? If you ask specific questions you might
get better response.
