I wouldn't be concerned more about the performance with this configuration I'm looking more form a maintenance perspective - I have to draft some maintenance for our infrastructure team whom are used to a standard NAS storage setup which Cassandra obviously breaks.

Ultimately, would keeping the cassandra service separate from the data and/or commit logs benefit from a recovery perspective where if we lose the primary partition, we could restore that from the data that is still on the secondary?

What it considered best practice?
What kind of routine health checks are best to look for daily? monthly? annually?

Basically how do you up-skill a technical infrastructure team to be able to maintain a Cassandra node ring?

I don't think it makes much difference from a performance perspective
at all.  You might want to create a separate LVM for your data, or
entire /var
