I was going to recommend you AU Lit with 10X and 2% additional CB features. AU doesn't give Cashback or points directly on insurance but you can loan any prepaid card such as payzaap and use that to make payment.
But your monthly payment is huge. If you can make multiple payments then you can check out AU Lit. 10X points feature has limit of 25K points per billing cycle and 2% CB has limit of Rs. 1000.
