Ensue some character development with your starter, foreshadowing that this will be the last game.
Your "rival" is a childhood friend of yours. She starts her adventure some time ago and she's gotten so strong you see her as your example of how to do things. In the story climax, you both are conflicted about your vision of the world. You only battle her in late game, where she highlights how strong have you became, before you face your last challenge.
Maybe an Open World game would be okay, giving more possibilities to end your game than become the Champion.
For the Postgame, you can use the Open World to complete sidequests which will make you encounter with characters from other games. This game takes place 20 years after the original Red and Blue (17 years after GSC), those characters have grown up, and talk you how their adventures have ended and what are doing at the moment.
