In general, a final table should be played conservatively. But the type of game you will have to perform depends, among other factors, on the size of your chip stack.
If you are the player with the most chips on the table, you can apply more action to put pressure on your rivals, and thus be able to take the wells. But you should not abuse this behavior either, as you will often be caught with better streets.
If you have the smallest stack, your game will be based on playing strong hands or also hands with overcards and middle kickers (A-8, for example) and the movements most applied by you in these cases will be: all in / fold.
And if you have an average stack on the table, your game should be as conservative as possible, looking for opportunities to get the most profit with your high hands.
