Lenses on a budget

Hello!! I just bought my first ever professional camera, the fujifilm XT5, & I am so excited to use it & take so many pictures. However, I’m a bit overwhelmed by the amount of lense options. I was wondering if anyone had any recommendations on lenses on a budget? I’m aiming for at least below $600, I’d say $700 would be my max. I don’t wanna blow my whole paycheck but i really would like to get one before February 1st when I receive my camera :)
