Piece Recommendations

I’ve been playing flute for about a year and a half and i’m finally grade four. There is this one piece by Bach, Badinerie from Suite no.2

I’ve wanted to play it for a while but it’s of course out of my skill range 😅 So I wanted to know what pieces could maybe help my technical skills to first play this piece, and second I guess reach grade 6. Im also preparing for district auditions so this would be a great help for that too.
