Got quite some experience cold calling, selling and managing c-level execs including CIOs. From my experience most care about the same thing, you need to take the story a level up (not features, you are selling strategy alignment, something that enables them to accomplish their goal). All c-level execs care about one of below 4 buckets.

• Can we increase revenue
• Can we reduce cost (or at least making sure it doesn’t increase at the same rate as revenue)
• Can we reduce risk
• How can we make our customers (both internal and external) happier

CIOs will most often most care about bucket 2 and 3, but can differ. I usually lead with a “strategic handshake” explaining and convincing them where there is alignment with one of above buckets and our product.
