I'll give your three right now & perhaps more as I have time to think clearly & come up with them.I really don't see any parallels. The stance is different, the swing is different, the scale is slightly different, you only use one ball in golf.
I'd love to know what is similar besides a ball going into a hole, in which case it would be similar to foosball, basketball, hockey, soccer, lacrosse, pinball, ball-and-cup...
Just because it is one guy at a time hitting a ball with a stick doesn't make for any equipment or technique crossover.
1) When I'm putting, especially the short ones I keep my head down & listen for the ball to go in the hole. Works for pocketing an object ball as well.
2) When playing pool it is wise to keep the cue ball on the correct side of the next object ball as you play your pattern. In golf it is also pretty damn smart to try & position the ball to the correct part of the fairway to attack the pin.
3) In both golf & pool setup, aim, alignment etc is 100% crucial as a start to hopefully send the cue ball & golf ball on the best path.
