How does Coinbase fee structure work?

Could you elaborate on how Coinbase's fee structure operates for its users? I'm particularly interested in understanding the different types of fees charged, when they are applied, and if there are any strategies or ways to minimize them. I've noticed that fees can vary significantly depending on the type of transaction and the user's account status. Additionally, are there any hidden costs or additional fees that users should be aware of? Clarifying this information would help me better manage my cryptocurrency transactions and overall costs on Coinbase.
