Just don't have kids... the spouse gets everything and can decide what to sell or trash.
Easy.
Now it's just a race to die before she does so she has to deal with my estate and all my junk rather than me having to deal with hers.
All jokes aside, you should get with an estate planner, one well-versed in your state's laws (because it differs state-to-state). Having a will in place helps, but it's no guarantee that it'll be followed. The executor only has to do what's in the best interest of the estate (not the heritors technically, but what's in the best interest of the estate is what's in their best interest, it's kind of complicated). At any point, any potential heritor can contest the will, or the named executor, or the chosen executor's actions.
The process generally goes that all money assets get consolidated into an estate account (generally any stock options get sold, but retirement accounts might have their own separate distribution). Creditors get paid first and if there's not enough to pay them off, physical assets get sold until they can be paid off. Then you can sell all physical assets, distribute them, whatever.
I'd caution against collectibles unless you hate your chosen named executor. Often times whether something is of value to a niche community they can be sold off for higher money, but there's so much crap to do that nobody wants to figure out the value of your rookie cards or collectible coins or whatever else. They generally get tossed or sold at an estate sale for whatever people will buy them for to move them quicker, there's bigger fish to fry and more important stuff to deal with.
