Questions for Musicians

I need some professional/musician advice from people who are not afraid of 'ethnic' instruments. I'm trying to pursue an instrument, but I don't know which one to go with based on my voice and portability. I'd thought between Piano Guzheng: https://www.youtube.com/watch?v=5TQ8cOwhgKo Hurdy Gurdy: https://www.youtube.com/watch?v=L5oQt23yfyk I have a soft voice here: (Rubia): https://static.smintro.com/production/uploading/recordings/12103424032966027/master.mp4 I have a background in piano, erhu, and harp. I'm not afraid of a learning curve. I need to sing with the instrument. I plan to busk, so portability is also a key. My shoulders are fucked, which is why I cannot play erhu anymore. Which is the one instrument I have on hand. So.... any advice? What instruments have you played?

I absolutely love the hurdy gurdy, however, with your background((And shoulder), the first one(Guzheng) would probably be a more natural transition. Either way, grace us with a musical update whenever you decide. :)
