So regardless of what school he chooses, it's up to him and just like you said, his father is very supportive of his sons and he only want the best for them.
That's the most important thing, we already have Lebron James his father who is going to be a hall of Famer soon, so it's enough to have one in the family. Well, as long as he would just enjoy basketball and let things come around, I mean no pressure, then maybe one day we will see Bronny playing in the NBA and Lebron would be happy cheering for his son.
LeBron had enough pressure when he was still in highschool as there was already a lot of offer for him even before he set foot in the NBA. A lot people expect him not being a bust and he did live up to the hype.
Now, IMO as much as Bronny enjoys the game of basketball, but it is inevitable not to feel pressure when your father is one of the best to ever play in basketball. People expect him to be as good if not better than his father LeBron.
Bronny must not only develop his physical basketball skills, but also his basketball IQ. He must, but even if he will improve, he will not be as good as his father. Lebron when he entered in the NBA, he was already playing like a superstar, but due to lack of experience, he has not won a championship until he joined the Heat. So for Bronny, I think being an NBA player and playing for years would already be a big achievement.
