My list isn't very long, I'd still try to live mostly modestly even if I was emperor
-A small house in the countryside where I can get away from the politics of the capital and spend most of my free time, I'd order some infrastructure to be built for faster Internet connection though, but I mostly don't want anyone near me besides 2-4 of my most trusted guards. I would still have an illustrious palace for the sake of legitimacy but I wouldn't want to spend much time there
-A harem of 365 of the country's most beautiful virgins, they will be forced to live in an isolated chamber of the palace, at least until they hit the wall and I dismiss them. They won't be allowed to have any contact with the outside world or males besides me under the punishment of execution. I would prefer to keep my virginity because I know none of them could ever love me, I'd mostly have them as a status symbol. Maybe I'd spend some time with them occasionally and see if I can resist the temptation to fuck them
-The most beautiful and intelligent KHHV foid in the entire empire as my personal secretary, she's also forced into chastity. I might honestly have her vagina surgically sealed to ensure this
-Imperial regalia and jeweled ceremonial armor so I can larp
