I’m a woodwind person. I have the most fun with flute, but the sax is more accessible in my experience. You could also have fun with a penny whistle, there’s a lot of rep for it and you can play bagpipe repertoire on one too.
The biggest thing is to practice and respect the instrument. There’s a lifetime of mastery ahead of you, and approach it with patience and hard work.
Also, have fun!

There’s also a puzzle somewhere with a ladder you gotta shoot with the slingshot, that’s a little out there
Edit: I was describing the deku tree. Sorry bout that
