Phone for a 10 year old, what rules and limitation should I force?

Ok, I know we should wait longer. I hope you will not destroy me for being a bad parent. But I don't think we can wait any longer. He is going to middle school next year and today (5th grade) already 75% of kids in his class have phones. He is miserable, can't stop thinking that he is "worse" than anyone else and that's the last thing I want him to think. Also he got 100% on his finals despite doing accelerated math (6th grade in 5th grade) so he deserves it.

He will be getting one but we will set some rules and limits. Here are ones I came up with. Can you come up with other very important rules I may be missing?

1. ZERO social media 2. ZERO youtube/tiktok and similar 3. Phone stays at home unless it is really needed for some reason when he is out 4. No phone at school 5. apple store will be under my control (apple family settings )

What else?
