To deliver faster, more cost effective data service to customers, carriers must re-use existing spectrum licenses with newer, more efficient cellular technology. Old 2G/3G infrastructure makes way for new networks, and older cellular devices must be retired. 4g may have a decade left before complete absence, but its footprint is already shrinking where 5G is available.

Upgrading, for example, 100 antenna sites is also a major truck roll cost, so we want to get it right the first time.  Physical space and power limitations usually rule out 1U rackmount refurb Cisco terminal servers, which is why we need 0U gear. Yes, I can cobble together a raspberry pi and some hats and cables and dingles and dangles and make a science fair solution. But I need something that is commercially supported, won’t have me scratching my head later about what version of the Ubuntu is going to work, and won’t randomly fry its electronics during a power surge.

Fair enough - if the bulk of your OoB use-case is remote (cell) sites, 
your typical options won't work or will be limited.

Oddly, in our parts, we find remote, non-city locations, tend to keep 
their 3G/4G status, or don't even get considered for 5G at all. But I 
guess this will vary by market the world over, so I could see a remote 
site in Norway, for example, having 5G vs. a remote site in, say, Egypt, 
doing the same.

I think what you probably want to consider for the long-term is 
decoupling the device from the network media. If you can attach a MiFi 
router via a USB port to a cheap device (like Mikrotik), this would help 
keep costs down as mobile operators deprecate GSM data technologies in 
the future. I like Mikrotik because in addition to being cheap and 
feature-rich for basic network access, the firmware is regularly 
upgradeable unlike typical consumer-style CPE's.
