Byakugan also can't read minds. Neji was reading Hinata's body language. All Neji really needed was relatively basic knowledge of psychology to pull off what he did. He did the same with Naruto.

As for Hiashi, there is no sign of his Byakugan being active and it was played for laughs.

We actually saw insane tracking abilities of the Byakugan in the fight against Kidomaru. Fast barrage attacks looked like they were frozen for Neji. 3 Tomoe was able to read normal Narutos movements and Neji was easily able to follow normal Naruto movements. The normal Naruto wad done pretty early on in the fight.

The mind reading is something interesting. As you can see in those stated chapters was Neji's Byakugan on. He was reading the intention and function of every movement Hinata made and did that to Naruto too. That definetly looks like some kind of mind or intention reading. We should not forget that scene when Hiashi activated the seal of Hizashi when he was sensing an evil intent towards him. His Byakugan was activated too.

Coming to the Hiashi scene in Boruto. He was able to perfectly tell what Boruto was thinking. Considering those reading abilities of Neji we saw is that a pretty huge hint that Byakugan might grant some mind reading. You could call it a joke episode but it wasn't as it was an episode dedicated to the Byakugan and it's rough background.
