Another brand that should work with Meraki is ZTE. Sadly, USB stick are disappearing from retail and most portable LTE modems nowadays are MiFI. Integrated LTE modems from most brands even Cisco often lack complete LTE band support.
I purchased the below one, its unlocked so it should work with ATT/StraightTalk, although I used a T-Mobile sim in it. I have attached to laptop, desktop, MX64, and MX67, no issues found. Usually gets better speeds than your phone in the same area.
