According to what I understand, I would recommend you to use the Intel® NUC6i3SY or Intel® NUC6i5SY, to go under all aspects you mentioned, like watching videos on HD resolution, and do other tasks.
Will the 5PPYH model suffice for my basic computing needs? Yes, it will do the basic computing needs.
Here you can take a look on a comparison between Intel® NUC6i3SYH and Intel® NUC5PPYH
Btw, the USB Bluetooth adapter won’t be necessary.
