I'd be inclined to take at least some of those weeds and burn them into charcoal. There are lots of threads here on ways to do that, ways to inoculate the finished charcoal to make biochar, and the benefits of biochar in garden soil. From the way you describe your soil, it could help a lot!
For composting the rest, I think maybe you've got too much "brown" and not enough "green". It might be that if you used an enclosed composter and mix the weeds with damp material, such as kitchen scraps or grass clippings, they'll break down a lot better.
I don't think baling is a good tactic in this case. Straw bales break down slower than loose straw, because the bale keeps the inner layers dry. And if a bale of straw does get enough moisture inside it to break down, it can sometimes produce enough heat to start itself on fire!
So, my recommendation would be to take that garbage can you were thinking of using as a baler, and turn it into a compost bin instead. When mixed with wetter materials the dry, woody stuff will break down fine. And think about taking some of the woodiest pieces and using them for biochar.
(If you decide to try baling anyway, please let us know how it goes. I'd be happy to be wrong about that. Just be careful about the fire risk!)
