Get the pointtangent through closest location and plug it into the Point At port of a Direction to rotation node and get the pointnormal through a closest location node and plug it into the Up Vector port of the same Direction to rotation node. That tends to give a relatively stable result which doesn't flip much and smoothly rotates with the flow of the curve.
