We've been living in one yurt, then two connected by a doorway, since 2009. We've gone for wooden tongue & groove flooring and wood burners. We had them from new, but you should be able to pick up a frame second hand. We've had various issues with covers - even polycotton not lasting as long as it should. But in the States (we're in France), I think you have more - and better - options.
The sound of the wind isn't something you need to worry about. It's the rain. When it's very heavy, you need to shout to be heard but it soon passes. WInd can be unnerving when it's very strong and you should be confident that trees won't fall onto you at night. Advice from someone who knows about trees will help, while you build up some knowledge of trees for yourself. The beauty of living so close to the rest of the world can't be understated. We're not just connected to the weather by our thin tissue. We're aware of the comings and goings of seasonal residents, like owls, golden orioles, cranes, midwife toads, deer and all the rest. We had dinner at a new friends' house the other night and it was strange not to know what the weather's like. (For example, the sun just came out from behind a cloud.)
Don't underestimate your needs for dry storage for wood, tools etc. In summer, it's far too hot to be in the yurt from 10am to 7pm. Our guest yurts are in shade, so they're fine (we have a small yurt camp), but ours are in full sun. We eat outside up to three times a day when the weather is good. So you should plan for that. I'd aim to be close to a natural pool for swimming. For an insight into yurt living, you could check out the blog I've been keeping since 2007:

Good luck. I hope as much as possible goes well for you.
