You can significantly drop power draw by lowering clocks and voltages. At the same time you risk making the system unstable. You'll have to rigorously stress test it to make sure it's actually stable.

Nothing inherently insecure about RPi in specific. Same rules apply to any device in your network: if you expose services to the internet, you are introducing potential security risks. Does it have to be open to everyone? Should you limit access to specific known trusted clients? Can you use VPN rather than exposing it to internet? Is your authentication scheme robust? What data does the device have access to and does it NEED to have access to all of it?
If your device only makes outgoing requests then your main concern is whether you trust the service its polling.
There are some Optane drives with m.2 interface like P1600X. Optane may not beat bandwidth records, but their low latency makes them ideal for when you have to do lots of smaller read/write operations like when using databases.
