Quote: "Quite surprised FBX is not listed. "
FBX may not have been listed because developers have to pay a licensing fee to use it. The other formats, like GLTF and OBJ are free to use. Also, Autodesk keeps updating the FBX format, making it a bit of a PITA for developers to keep up.
Quote: "but unsure of the other 2 formats. GLTF and GLB. Certainly not familiar with those 2, not even sure which support animation either"
You should read up on GLTF:
https://www.khronos.org/gltf/
It's pretty robust. It supports geometry, multiple UV maps, textures and materials (so you can do your PBR right in your 3D app of choice), animations, lights, and more. You can export individual models or complete scenes, etc. It was designed to be a universal 3D file format that anyone can use for 3D apps, 3D games, etc.
An explanation of the differences between GLB and GLTF can be found here:
