I've skied in Lyngen, Lofoten, Sunnmore, Jotunheimen and Romsdal, all are amazing if the weather is right. There's peaks everywhere. I've skied lines from the guidebooks, and I've tried my own by looking at maps and by just picking something that looked nice on the day. The popular peaks can be quite busy on a nice day during the holidays (I've seen around 30-40 people skinning up tomasrenne in Lyngen, and about 100 on kirketaket on a sunny saturday) but usually there's no-one else. If you're in to couloirs there's lines everywhere. I know a couple with a vertical of >500m that I don't think have been skied before, but I'll keep them for myself
Of course you could always try Svalbard, but it's probably best to do that with a guided trip as the logistics are complicated and expensive, not to mention the polar bear factor.
It might be worth posting on the friflyt forums as I suspect there's people on there with way more knowledge than here.
Friflyt does all the topptur books, there's the general norway one, and local ones.
You'll need a car, which is about 1000nok per day, and accommodation can be hard to come by. For airports pick the cheapest one within about 2-3hr radius of your destination. Note that sometimes it's worth connecting by boat. E.g. fly to Bodo, then get the boat to svolvaer and rent a car there.
