Yes those motors are the correct type (high current low inductance). Other than that, the X and Y motors should be same model. Also if its a machine with dual Z motors, then those should match to each other. But other than that, Z could be slightly different than x and y. And at last, E could again be different from all the above, probably if you use a direct drive extruder you want high torque for e. If you have geared extruder, then motor could be smaller because the gears will increase the torque.
For a machine with independent x and y, like a moving bed, there is a moving assembly on x and another moving assembly on y. Only the one with higher mass counts for getting benefits via weight reduction. E.g. i dont know what is your situation, you should probably try to evaluate which of your axes weights more, the bed or the extruder carriage. If the bed weights more, a further weight reduction on x carriage does not bring benefits. If the bed is lighter than the x carriage (incl extruder), then it is the case that lighter x would be beneficial.
