Participating in tournaments with a higher time control (rapid or classic) generally expands your thinking, because you take time to sit and plan your next few moves and all the possibilities that can arise from those moves. You start to see patterns on where to improve because you can reflect on your strengths and weaknesses from just one rapid or classical game. This level of reflective thinking is impossible with hyper-bullet, bullet, and blitz games as you need to think faster which opens possibilities to make countless mistakes compared to longer games.

Some may play an aggressive, while others tip-toe over the risks by playing more defensive. Your post highlights the importance of participating in tournaments chess-tastically! Well done!!
