Well with the exception of Zelda and Xenoblade Chronicles series, Nintendo first party games are usually less demanding (see Arms, Nintendo sports series 2d kirby + mario games, Mario sports series, Warioware, Mario Party etc).
Zelda doesnt even have voice acting for its characters most of the time and its games use simpler textures than lets say Horizon Zero Dawn, Last of Us, Gears of War 5 etc which means that the development costs are lower.
Even so, their games are generally polished and well thought of and as the Switch generation showed, many of their franchises actually grew considerably in sales (Kirby , Xenoblades, Metroid etc).
