Just one question; the 10 Gauge wire is really thick, can I successfully screw down the ground wire with a green ground screw as pictured?
Or should use that all copper terminal lug to attach the ground wire to the Metal gang box?
I have those grounding clips too but the slot where the ground wire is supposed to pass through looks too thin.
You can probably wrap the ground wire around a ground screw, you you're right, might be tough with the 10GA ground wire.
So it could be easier to use terminal lug to attach the ground wire to the box. Or use a ground bar like this:

Don't mess with those grounding clips. Too easy for them to come off.
I am certainly not a fan of using the conduit as a ground if running conduit and pulling individual wires, too easy for conduit to come loose and then you lose your ground. I would always pull a separate ground wire.
