For painless landing on high-G worlds, what's worked for me is to not touch the vertical thrusters (up or down), and descend with forward thrust at a shallow angle. I'll start at maybe -20 or -30 degrees, coming out of glide. As I get lower I'll slowly level out. Once really close to the ground, I'll probably be maintaining a pitch of less than -5, and I'll have been gradually reducing the throttle too. Eventually you can just sort of "kiss" the ground at a slow speed, and lock down. Or alternately, come to a stop only a few meters above the ground, and then very gently tap the downward thrust, using an analog stick. The latter is riskier because you might misjudge your altitude, or how gently you can use the control.
I usually take at least a small amount of shield damage. My last notable high-G landing was at the 45 G planet using my DBX, with no shield damage. I used the forward-throttle-only method. (Screenshot taken only seconds after locking down).
