.obj is pretty standard and the only one I know well. There’s lots more judging on the export options in Blender.

Without getting into an .obj loader the “stanford dragon” is probably a good example to have since it’s common starting point for OpenGL shaders and vertex data is easy to copy and paste into a file.

Actually WebGL is like OpenGL 3 core so you must have vertex buffers and shaders, which comprise the bulk of the complexity. I could have removed the matrix transform and used OpenGL coords and removed the interleaved vertex data and colors which added some complexity. You’d probably want to actually learn OpenGL from one of the multitudes of sources before looking at demo program since the learning curve is pretty step.
