Since jumpstarting did not work, that would eliminate the battery as the cause.
At engine room relay box, unplug the starter relay and test terminal # 5 for battery voltage with ignition turned to START. If voltage is not present, check the ignition switch.
Use a fused remote wire to apply battery voltage to terminal # 3 of the starter relay. Starter should work. If starter fails to work, give it some knock and repeat above. If starter works, it is failing and has to be replaced.
If starter does not work, check the starter solenoid wire connection. If it is loose or dislodged, retighten/reinstall accordingly and retest if it cranks.
