Anything of value that survived your death- property, money, IP rights, etc. now are part of an estate which is administered and distributed according to your will and/or state law. Other than your state’s law and your will, it’s not up to you what happens to your stuff after you die.
Artifacts of your existence that you did not own, like your extended family’s home movies or that time TV news caught you in the background or your friends’ photos, don’t belong to you (never did) so I’m not sure you can do anything about that, and it poses an interesting question of whether your likeness could be reconstructed from artifacts that are not part of your estate.
It would probably be worth having a law that says that your likeness is part of your estate, and then it can be covered by estate law.
Of course right now you could probably sign a contract giving rights to use of your likeness, and have terms and conditions that would cover post-death scenarios ; I have heard that some celebrities are already entering into such contracts for money.
