Unfortunately, I'm not well - versed in all the fanfictions out there to give an exact recommendation. But you can explore fanfiction platforms. Look for stories that feature strong female characters in a fantasy setting, especially those with a guardian - like figure. Also, look at the reviews and ratings of different fanfictions. If a story has a high rating and reviews mention themes like rebirth and a special bond between characters, it might be similar to the'reborn is fem harry's sun guardian fanfiction'.
I'm sorry I can't really recommend similar ones off the top of my head. You could try searching on fanfiction websites using related tags like 'female Harry', 'guardian' and'reborn' to find similar stories.
