What would be the best way to rig this?

Im not a rigger or anything, but i want to set my model into a pose, just so i can showcase it. this is what it looks like…

Armature bones, make a skellington in edit mode, then weight the mesh to the bones (skinning).
This takes time and practice… If you want it to look good.

Though if you just wanted to pose the mesh, you could save as a different file, then rotate the limbs with pivot point set to 3D cursor. Then render some images.
