It will be Burn who would be a great Capitan tbh. I'm a bit torn on Bruno, I'm not sure he's cool enough but given the chance he could be really good. I don't think the other two.
Wherever you sit on that he won't be in any short period of time. Too many issues to deal with elsewhere.
It would be Burn imho with Longstaff as VC. Maybe Pope as he is the most likely to play the majority of games but not sure what he is like as a voice in the changing room. Love Bruno and his passion but wouldn't want to give him that extra weight to take on, just let him concentrate on football. Burn and Longy are local lads who it wouldn't affect. Big Joe standing off with club over wages rules him out. Botman is probably just a little bit to young currently but in 2/3 more seasons think he will be a captain at the club (if he's still here).
Captains do boring **** too like There's a reason they're often the solid boring one at a football club
