Meditation and yoga nidra scripts have been immensely helpful for me in terms of accelerating the transition to sleep, so they involve taking a few minutes, 10 to 30 minutes or so, just like you would for a nap, and just listening to a script, almost passively, and it has you do some particular patterns of breathing and some other kind of body-scan-like things that can really help people learn to relax, not just in that moment, but get better at relaxing and turning off thinking in order to fall asleep when they wanna do that at night.
