The right-hand rule for conductors must be used with which current direction convention?

The main idea is that the right-hand rule is defined using conventional current direction—the flow of positive charges from the positive to the negative side. When you point the thumb of your right hand in the current direction, the curled fingers show the direction of the magnetic field around the conductor. This convention keeps the rule consistent with Ampere’s law and other electromagnetic principles. If you used electron flow, which moves opposite to conventional current, you’d predict the opposite sense of the magnetic field. The rule’s result is the magnetic field direction, determined by this conventional current input.
