You can’t really match in Fireworks what you get in Flash. The apps were developed separately by separate teams and use different rendering engines. Maybe you could find some settings that match, or at least get close to Flash’s, but I don’t know what they are. You’d have to experiment.
But there are some cool features with Fireworks strokes. Like pressure sensitivity and the scrubber tool which lets you alter that sensitivity after the path has been drawn.
Granted, strokes are a lot more confusing there, and in more ways than just being more feature rich. I even tried to make my own stroke/brush panel to simplify things but never finished it. I wonder if that made the source dump…
Yup, there it is!
That looks like it got further along than I remember
