I don't really find myself rooting against any players in particular, but I do like to see an exciting finish (like 99% of fans). So to that extent, I'm usually rooting for the players who are behind and hoping that they overtake the leader. The only time I'll root for the leaders is when I feel like there is something historic happening (old player leading, an Am, a player like Tiger chasing history, etc). I find it hard to get excited when guys like Scheffler or Rahm are just on cruise control. I don't really have any favorite golfers, I just like interesting endgame situations.
