I have similar wants. Just a standard house, maybe some land for a bit of gardening, and a workshop to make things. Donate to certain charities and open source projects etc. Travel a bit.
But they’re one little thing I’d do that would definitely show I’m rich:
I’d travel to local forest parks around the world, and bury actual treasure. Like a 3 gold bars. In in actual chest too. Maybe every now and then I’d do smaller treasures that are like a fancy sword or platinum ring or just medieval armor. Idk.
Then I’d go to the local university and set up riddles they’ll lead to a part of a hidden map, with the map being hidden both throughout the university and maybe online too, depending.
But it wouldn’t be a straightforward map. It would be a map to a random house built near the park. And somewhere in that house, would be the final map leading to the treasure.
Why? Because the world could use a little bit of magic adventuring I think. That’s something that just doesn’t really exist anymore in the modern era, in a way. I feel like finding treasure and going on a treasure hunt is something a lot of people as a kid probably thought would be fun.
And second, university students can always use some money, so they get first dibs too.
Likewise when I die any children I have would have to go to a mini mansion and solve the puzzles in order to get my last will that grants the finder my money.
I think it’s the one in New York named Spyder Mann
