Could be wrong but is Tekken 8 technically the first traditional 3D fighter on the Switch ecosystem? 

Nope, 3ds received a version of Tekken 6 for PSP but with 3D features and Wii U received a Tekken Tag Tournament 2 port.

Edit: Forget about it, I saw Nintendo in your phrase, but you said Switch :x
