Keith,
That sucks that your ISP is going (further it sounds) into the crapper. I suspect that your option in our area is likely Verizon of some kind, though maybe comcast/Spectrum competes in that area as well.
In any case, to have a static IP they're likely going to force you to have a business line of some kind. Looking on the Verizon website "Fios Business" is $50/month for 50mbit up / 50mbit down.
As for keeping your IP address, I agree with you, I don't see much hope there, but who knows.
As for putting stuff in the cloud, it's just a virtual machine running who knows where.
Though from a pure linux nerd point of view, I've come to love Linode. It's basically a cloud provider built by linux geeks. Also if you look around there are all kinds of incentives where they'll give you a 100 bucks to screw around.
The other cloud provider I've tinkered with is digital ocean, as well as AWS/GCP/Oracle cloud.
The pro/con of going to the cloud is they hide most of the knobs..
Tim.
I am leery of the allegiances of any politician who refers to their constituents as "consumers".
