Couple of sites which should give you some insights; Mobile Internet Resource Center & the Peplink forum. The latter has some interesting posts associated with 5G with their equipment. You did not indicate your current equipment that you are considering for upgrade, but, we have been using a Peplink Max Transit CAT-18 for over a year. Have been very pleased with it.
Regardless of what, or if, you decide to go with, make sure your cellular data plans will work with the equipment. Sometimes, establishing cellular connections with new equipment can be very frustrating & sometimes it's seamless.
