You don't train cats you compromise with them.
It's kinda like comparing training a human living with you to training a dog. For most dogs and humans it's entirely different. You don't really train a human roommate or cat so much as let them know what you don't like, try to provide alternatives they would prefer, and then hope they decide to follow it. To stop them scratching the furniture you provide a scratching post they like better anyway and then express your dislike of furniture being destroyed. Instead of "don't scratch that" which is how most people handle dogs it's more "I'll give you something even better to scratch if you don't damage my couch". Compromise instead of commands.
You can teach a few tricks if you have a good treat they are interested in, the cat already has a tendency to do the action, and you can keep their attention long enough. Usually cats do better with learning practical things than tricks. If it's useful a cat will learn how to do it but if it's just a human asking to do something for a silly reward they don't really want to try.
