A handbuilt wheelset with Stans rims and DT-240s hubs (or pick another reasonable quality hub for less cost). I would not buy a pre-fab wheelset of any kind, but between the ones you mentioned I would lean towards the Specy. At least it should have a good warranty if you get it from a Specy dealer. Stans rims rule the industry for reliable, simple tubeless setups though...nothing really compares, while other solutions can be made to work.
Yes I run a bigger tire up front sometimes for traction and cush, this is pretty common. It is nice for general riding, but does slow things down a bit for climbing and XC rolling stuff to have a bigger tire, compared to just a pair of 2.0's. Can improve speed for descending if it is technical terrain.
