Yes, there are other thoughts out there, be sure. :)
Let's start with wood-working skills. I worked with wood for a living - the only work there is was at small furniture factory - so wood-working skills I already have, and they, basicly, come down to two: cutting and grinding by the carefully scribed lines; a lot of different equipment is used for this, but not a lot of different skills. Quite honestly, those two activities bored me to death when I was building lockers and tables, and they bore me now. If I'll never smell the smell of hot wooden sawdust, I wouldn't regret it. :)
There is, of course, another skill, which I admire - carving. Scratch-build rich and exquisite carvings on ships fascinate me; and I would be the first to admit, that it's a true art; however, only a small minority of ship-builders are able to produce good carvings. And I will never be amongst them, I know it for a fact. So, why do third-rate job?
Which points us in another direction - level of details. Wooden kits I've seen (I admit, I haven't seen a lot of them, just a few relatively cheap (less than $200 each) kits from Mamoli and Constructo) have unsatisfying for me level of small details. Their hand-rails, top masts and yards, small boats and most of the small details look thick, big, somewhat clumsy and out of scale, for most parts. Their metallic parts do not look seriously superior to similar plastic parts, and sometimes really inferior. Wooden sheave blocks and other blocks names of which I don't remember in English right now are better than plastic ones, because plastic is simply too brittle for them, I think, but they can be used for plastic models as easily as for wooden.
As for "skills same as the skills of shipwright builders", well, it is my unsupported by facts opinion, that other than general skills of cutting, grinding, and fastening, it's a pure wishfull thinking on the part of wooden modellers. I myself, of course, have never built a ship; however, I've built two small boats for fishing in rivers, and I assure you, that there is not much correlation. For example, there is a lot more tar, swearing, sweat, and brute force involved. :) And, of course, months and months of buckling, maceration and drying of wood. And no, shipbuildres don't glue planks with white glue, nor do they build hulls in any way close to the hulls of models. :)
The beauty of wooden models is in a warm, alive and sometimes even nearly luminous colors of natural wood. That's why the wooden models look so good, that's why they are valued. But that's the property of wood; not the skill of modeller, who may enchant it with varnishes and stains, but can't, in my opinion, take the praise for it. Once painted, wooden models look no better, and often worse, than plastic models.
For me, the main skill in plastic models' building is in painting. Painting plastic as wood is the hardest challenge.
And, of course, rigging is absolutely the same in both wooden and plastic models, and depends only on a desire of a modeller to spend more time on it.
As for limited choices... Well, I have the following projects which I've already decided I will do: Revell's Golden Hind which I've done; Heller's Le Glorieux, which I'm doing now; Airfix'es Vasa, which is following; a pair of gorgeous, even if not historically supported, chinese junks; diorama of Pinta, Nina and Santa Maria, which I most definitely would build, but for which I haven't yet decided which kits to take; Darwin's "Beagle", "Great Western" and river steamboat "Robert E. Lee", if I remember correctly... That will occupy me for the next, like, 5 years? Of course, most of those ships are from dusty Old World history, which is not interesting for everyone, but still, is there such a small choice?
