Hello Hassaan, We use cassandra helm chart[0] for deploying cassandra over kubernetes in production. We have around 200GB cas data. It works really well. You can scale up nodes easily (I haven't tested scaling down).
I would say that if you are worried about running cassandra over k8s in production, maybe you should first try setting it for your staging/preproduction and gain confidence over time. I have tested situations where i have killed the host running cassandra container and have seen that container moves to a different node and joins cluster properly. So from my experience its pretty good. No issues till yet.
