My daughter has just started private piano lessons at home and has the opportunity to start peripatetic music lessons at school next year (y4). I think the clarinet would be a good choice for her and would give her the opportunity to play in a group (band or orchestra) a bit further down the line should she wish to. She wants to do the guitar (because her mates are doing it). I think the guitar is a) difficult to do well, especially if she's only receiving 20 minutes lesson a week in a group and b) is another solitary instrument when she also does the piano. What do you think?
