Can you verify the engine will physically turn - isn't stuck?

After that I would directly test the starter itself.

Ya, probably best to pull the alternator cover and take a look. Ugly sounds from there aren't good.

Ya, hard to say. It does look like some garbage got between the rotor and field coil. Your stator windings also look a bit burned possibly? Might be a good idea to ohm the stator and compare that to the book value. If it's burned/shorted it will have a different value.
