Interesting that the boot got a hole. Maybe, it moved.
Inner tubes won't really work reliably (that's why you use a boot). No surprise that the tube pieces blew.

That makes sense. The boots aren't meant to be on the road. They are meant to be protected by the tread (which means holes that are too big are a problem).
The Park boot is pretty tough. It will last longer than the other stuff you listed.

It seems your problem was fairly unusual. And you managed anyway. Maybe, carry more Park boots.
