You've mention jibbing, jumps and cruising which are all a bit different for stiffness and even shape. But since we both live in Ontario, I know you won't much powder and probably jib around alot around the hill. Go with anything twin that a bit soft, but not super soft for your weight. An Artifact, Signal Park, Kink, Dom, Jibstick, Jibpan ect would probably be too soft for you. Save on Signal OG Series Wide Snowboard 155 - Mens Snowboards Snowboarding Gear Equipment
That is a super nice all round board. It's soft enough for you to jib on, I am 150lbs so it was more of a stiff board for me to jib on. But it's Twin, has a soft tip and tail for presses, but is very poppy and a bit stiffer between the feet for control while ripping if the park is packed or you wanna do some drops. I ride a Signal Park Series and it's my current favourite. If I were your weight and height I'd be riding this for my primary deck. Park Series is very soft, but lets you jib like a pro.
Check this site out, I've ordered from them before their shipping rates are super cheap, but be ready to pay 50-60 bucks in brokerage to Ontario (apparently you can clame the GST back on tax return, but that's like 15 bucks =P). All in all, you'll pay about 100 bucks in shipping and save like 200 bucks. MSRP is way different in Canada too. If something is 300$ US MSRP it's like 480 CAD MSRP. Which sucks because 300 USD it only like 330 CAD. So ordering online isn't a bad idea, if you keep in mind the 100+ for shipping. Good luck feel free to post some choices, I recommend Signal Omni and Park Series to everyone too. I love Signal and Stepchild. But NS, Bataleon, Venture are all great too.
