So Naboo knew about Padmé and Anakin.
In the Vader comics a group of the rebels specifically loyal to Padmé attack Vader. They believe that Vader killed Padmé and at least suspect Vader killed Anakin either protecting Padmé or was in the temple during the attack.
One rebel, who was at the battle of Naboo, gets lightsabered right as he yells; “For Padmé!” And as he falls with his dying breath; “and for Anakin.”
Anakin must have been beloved by Naboo. He helped the queen get to coruscant to plead the senate, saved them during the battle, and has repeatedly saved Padmé’s life.
Padmé’s grave was also for Anakin and their children. So many people must have see her “pregnant” at the funeral and only felt more heartbroken. Not only did their former queen and current senator die, so did her entire young family. Wife, husband, and child.
Behind some wall in Padme’s grave is a hidden memorial for Anakin. Hero, Jedi, husband, father. A carving of Anakin holding his saber hilt looking asleep like Padmé’s sarcophagus.
Pooja and Ryoo going to visit “Aunt Padmé and uncle Ani”. Only remembering him through a carving.
One of the Naberries or Amidala handmaids showing Luke and Leia. Luke grateful to have some of his father’s legacy preserved alongside his mother. Leia is grateful for a place to mourn her mother and hero, and to know her maternal family.
Luke only going back to Tatooine retrieve something of Shmi’s and Obi-Wan’s to bring to Anakin’s memorial.
