just playing on long final with the aiming point
Herein can be a part of the problem - the "aiming point" must be the first half of an appropriate length runway. Any more particular than that, and you're setting yourself up for trouble in the early phases of flying. With lots of experience, you can pick a point, and gently touch the wheels within a few feet of it. With little experience, just get it on the ground nicely. Work on precisely
where you do that as your experience grows.
If you have chosen a runway of suitable length for a modest skill pilot in that aircraft, and you arrive over the threshold at the right altitude, and speed, and gently pull the power off, you're going to stop nicely on that runway, unless you utterly fail to attempt to stop. Focus on your landing flare technique, and staying laterally on the the runway, once the power is off, everything else will sort itself out in terms of runway length.
You are much less safe forcing the plane onto the surface 10 knots too fast, closer to the threshold, than allowing it to slow while still airborne, and overflying a few hundred feet.
