The slider expression has the same effect as connecting the slider to an expression component (i think), only more limited since the only variable available is the current value of the slider. I think the best solution is what you did at the right, use a percentage. You can't change the maximum value of the slider to curve's length each time the curve changes length. If you want the slider to represent an actual length (meters, etc.) set the highest value of the slider to the highest value a curve may have. The problem here is that for most curves you may set a higher value that the maximum length of the curve.
You could add an expression afterward that compares the slider value and the curve length. If the slider value is bigger than the curve length, then use the curve length as the actual value.
