I have a custodial account and I need some help! (Sorry I don’t really know what to put as the title)

I'm in middle school and have a custodial account (that I manage) I'm also very interested in earning money and I've done just that! I've earned close to $1000 since the start of the year and I'm curious about which stock/etf with a dividend I should buy to turn on drip for awhile. Any suggestions? (I will buy multiple stocks/etfs if suggested.
