What ever you do, remember the best experience is up to you at the end of the day. You will need to make sure you have used a cell map and find out where your internet towers will be. there are sites for this. also, use a decent antenna/modem. Get the antenna high in the air and pointed in the right direction. There are sites for cheep unlimited sims and others you can get that take a dedicated 5g/4g hotpots and make it appear as an iPhone for providers. I had a two sim card modem for the best setup.
for ease of use i would not use a pci coral. usb just is easier. passing the usb through to a dock or vm is easier. i use unraid and it was extra work to get the pcie vs usb coral setup. I have a nuc with a bunch of ssds for this kinda thing too.
