How do you evacuate with wealth on your person in a manageable form without getting yourself robbed/killed after SHTF? Are there lessons we can learn here from Venezuela?

Well, protecting "wealth" was not exactly something I had to worry about. I had a little set aside in savings, yes, but that was gone in a blink. I didn't have silver, much less gold to take abroad with me. But having gone through a communist-style post guard and learning about the hundreds of stories where those guys ransacked wealthy passengers dumb enough to flash their shiny jewelry in the nose of those guys, I can provide some advice.

The first thing you need to know is that customs at the border will be brutal.

Laws at the border can be and will be enforced. The ruling mafia issued "laws" that "allow" them (against our Constitution, which guarantees private property) to imprison someone because of  "strategic materials trafficking," or whatever their conception of that means. For those of you living in democratic countries, this may sound exaggerated. It's not. I'm being forgiving with my descriptions here.

People have been in trouble with the NGs because of wearing a large amount of jewelry. Even though it's private property, the loose term "strategic materials" was coined by the communist invaders to give the uniforms in charge the "justification" to rob people blind. Of course, these "materials" NEVER end in the country's pockets, but in the uniforms'. Your choices were to surrender your goods or go to jail. The world just looked to the other side as this happened in Venezuela, while in Ukraine, all kinds of military support are being sent. This is the sort of thing Venezuelans have been dealing with for a long time. You won't find anyone in the streets with a gold watch or brand-name designer shoes. The only ones who can afford that belong in the mafia.
