Quick answers
Can I say "good luck with", "good luck in", and "good luck on"?
Yes. "With" is very common for tasks or situations, "in" works for a period or activity, and "on" is common before tests, games, and trips. "Good luck with the interview," "Good luck in your new job," and "Good luck on your exam" are all natural.
Is "I wish you good luck" wrong?
No. It is correct, but it sounds less natural in everyday speech than "Good luck" or "I wish you luck."
