Slow when bass fishing can be good, but don't think you'll be able to make long runs to 'better' spots.
Wide means high initial stability usually. That's also good. You won't be doing any tight turns where secondary stability and carving hulls come into play on the kinds of water you describe. So that's good too.
Seems like a reasonable choice.
