MN72 describes that the Buddha (or an Arahant) has no pancaupadanakkhandha, i.e., no attachment to rupa, vedana, etc. And that the nature of Nibbana is not possible to fathom in worldly terms.
This is why sunnata is not “emptiness” in the sense of “emptiness in worldly terms”. It is only empty of raga, dosa, moha (ragakkhayo Nibbanam, dosakkhayo Nibbanam, mohakkhayo Nibbanam).
Until Parinibbana, Buddha (or an Arahant) would have a pancakkhandha, but no pancaupadanakkhandha. Both are absent after Parinibbana. But of course, nama gotta (records) of those pancakkhandha remain forever. That is why the Buddha was able to describe the lives of previous Buddhas.
As was discussed in the other topic, saupadisesa Nibbana (elimination of direct mental suffering) is experienced during the life itself. Elimination of all suffering is at anupadisesa Nibbana or Parinibbana.
