For me I would:

- Random car walks around the city (I would move to another country but before I would like to ride around my city. Idk, maybe I just wanna feel nostalgia before moving) (Also visting old places)

- Go to a fancy hotel and be alone myself sometimes (Maybe to watch a world cup game, watch the final episode of a reality show or maybe just chill in peace)

-It depends how rich but I would get a second apartment and put stuffs that I collect there or maybe just make a time capsule place (something very 2000s)

- Not really unusual but collect Pokémon cards lol
