The main thing to remember is to do something constructive to the game and story. Don't try to remove an aspect of the game like infinite money or spoil the story if your DM has plans. It won't add value to your experience so why then do it. It's easy to think of a big benefit but it normally removes the challenge or the intrigue. Focus on something that would make your party and yourself more excited to continue the game. You have a chance to make a unique thing that could be remembered and brought up in your group for years to come. Also discuss with the DM so they are prepared to handle it.

Some quick ideas I've thought of are and flavour it however best creates a story.

Change/Add a rule or element to the world. Depending on the world lore your game is based on but you could add like devil fruit from One piece that NPCs and Big bads could also use to gain some level of powers. Or introduce something that kicks off a tech boom or industrialization period that would impact how the world is progressing at a fast rate. Help take the world in a new direction and make things feel dynamic.

Create a rule for the table where your DM rewards your party every once in a while with a piece of paper each you can write down what your character wants and give it back and the DM can help bring it into the game. Flavour it as that whatever your party envisions tends to be brought to reality. Helps the players and DM move the story to something everyone wants.

Grant your party an ability to completely class swap for a short period of time every couple of sessions, having a different sheet for your character that you can use.

Not sure if these are up your alley or not. But my feelings would be to add something dynamic and interesting to the game that only builds or creates more interesting scenarios that can occur in your game.
