Figured it out. The trick is to lessen the MaxVelocity and increase the MaxForce. This will keep the part in air and slow down the approach rate. You can’t, unlike BodyPosition though, make the numbers math.huge, otherwise the same disappearing/overbearing force issue will occur.
I had both MaxVelocity and MaxForce as infinite when the disappearing behaviour occurred: same happens when MaxForce is infinite and MaxVelocity is even a small number like 10.
This is my result with a MaxForce of 500K and a MaxVelocity of 10:
