Deck Stain or Something Else on Milled Pine Siding??

These questions pertain to a summer cabin on a lake in northern Wisconsin. The cabin has milled wood siding with a convex shape that creates a log cabin effect. I don't know for certain but I'm pretty sure the wood is pine and dates from the 1930's--no finger-jointed young southern pine here. The cabin receives a good deal of shade from the trees that surround it.

The existing finish is being removed with a heat gun and a hand scraper. The siding is then sanded. The best part is that my sister is doing all this work 🙂 😀 😯

I am planning on using a semi-transparent oil-based penetrating stain on the prepped siding. Is there something else I should be using? Since Wisconsin is not a low VOC state I'm not restricted in the products I can use. Based on the reviews on this site I'm leaning towards the TWP 100 stain. Is there any reason I shouldn't use this? Considering the limited sun the cabin receives and the vertical orientation of the wood how many years can I expect to get out of the stain? Longevity is very important to me.
