The ignition switch at the back of your key assembly can also cause this.

Two ways: the switch can come loose from the back (three screws)
and the other way is the switch itself.

I have had to rebuild one once. Took it apart, cleaned it, put it back.
Then had one that was loose. Tightened it up and it worked.

The really good news is that your tests prove it is good battery and starter.
No - there is no ither fuse in the link to look for.
Pretty much fusebox.

And there is always the possibility of the neutral safety switch.
There must be an easy way to jump over that and test.
One not so realiable way is to move the shifter through the range with the key turned.

That block in the passenger (right side) fender well is a great place to jump
the car with some insulated pliers. Taught my neighbor that one for emergencies.
