I’m installing windows IoT and “The install process will begin shortly.” has been on the screen for a while. Is the os downloading? Did something fail to install/download? Safe to cut power?

Something has failed to download or your SDCard is fake or end-of-life.
You need to ask yourself "what does NOOBS give me?"
If the answer is "A way to install Raspbian." then you should ditch NOOBS and go with Etcher (from https://etcher.io) and plain Raspbian 2018-11-13 (from https://downloads.raspberrypi.org/raspbian_latest).
If the answer is "Multiple operating systems and a boot manager." then you should ditch NOOBS and go with PINN (from https://github.com/procount/pinn) which is a much improved version of NOOBS which won't exhibit the problem you're seeing.
If you choose PINN you need a 32GB SDCard to make it useful.
