I've experienced strong winds several times, most recently was a storm that blew in over night while we were above treeline. I really regretted not bringing a CF pole and trying to use a trekking pole, as I had to hold the trekking pole for an hour or so, while I know with the cf pole I'd been sleeping or attempting to.
These are probably the biggest things:
1. Strong tie outs , and staking , no ti skewers, at least ground hogs or longer CF stake ok, as long as put in well.
2. pitch tight to the ground, after all condensation won't be an issue in a big wind
3. Strong pole
4. Tight pitch
5. guyouts 2 - 4 ft up depending on height of tent
I believe round has an advantage here, but everyone has their own opinion. FWIW, I've had tents 9 ft tall that did not have an issue in strong winds when 1 -3 were met, 4 and 5 help, and make it more enjoyable.
