Do you have any service listening on port 80? If not, I'd close it in the firewall and disable the forwarding in the router. Also sounds like a bad idea to set your router security to 'low', whatever that means for your router.

I don’t think it’s comparable to Amazon Linux even, it’s more infrastructure oriented. From the Wikipedia page:

CBL-Mariner is being developed by the Linux Systems Group at Microsoft for its edge network services and as part of its cloud infrastructure.[5] The company uses it as the base Linux for containers in the Azure Stack HCI implementation of Azure Kubernetes Service

You don't mention what services yiu plan to utilize and the limits are different for each.

Another community will take its place one day, so no real value will be lost.

This is one of the reasons I'm using OpenSUSE Tumbleweed. It's been a solid distro for me.
