The way I did it previously would be to burn horizontally so that you had very little speed, turn the lander vertical and lock it like that with the ASAS.
Then just line your camera up with it so using IJKL with the RCS corresponds nicely and just come down slowly judging in relation to the ground beneath you as you come down.
More recently I've been landing without really using RCS, I'm playing with a gamepad so I can be quite controlled in ship yaw/pitch on the dstick and just come down slowly keeping myself lined up with the retrograde marker - so constantly cancelling out my horizontal speed.
By the time I'm nearly at the ground I'm cruising down with maybe 10-20m/s vertical speed and at most 2m/s horizontally - by that point its easy to land with a quick burst.
