Clarification on afterlife

So i'm just about to start a new campaign as a cleric in the forgotten realms setting and i wanted some clarification on good aligned afterlife's from any lore knowledgeable person out there. Its my current understanding that there are three main outcomes for good characters afterlife's 1. You are turned into an archon losing all your memories and will eventually be promoted to a higher celestial 2. You become an embodied petitioner and retain your memories to begin with but they will slowly fade and over the course of hundreds of years you will merge with the plane your on or even the god themself 3. You keep your memories and answer divinations from mortals, forever being a celestial call center operator. Is there anything I'm missing or is any of the info wrong? Any help is appreciated :)
