Your point 1 has been my experience and I DO NOT understand why the most upvoted post in this post is saying to have one on ones with every team member on the team and also to have one of ones with related teams. I can't think of a time when that has ever been able to happen, especially on outer teams. Yes, it is ideal. But most teams and people feel like they are too busy all the time and also I have found that if you ask too many questions, sometimes that can be used against you if you don't know the team dynamics at play.
Your point 3 validates that as well.
