Are there any hidden secrets or hacks in Squad that can help me adapt faster and become a more valuable member of the team, especially when I'm just starting out?

There are a lot of unobvious things in Squad that can help you in the game. For example, using environmental sounds to determine the direction of an enemy's movement, or being able to read a map to choose the best paths of movement and positioning. Also, feel free to communicate with the team: experienced players often share advice. And remember that Squad cheats are the key to mastery, so don't be afraid to experiment and learn from your mistakes.
