Pretty much do the same thing, I leave the pull tabs visible to make it easier to pull down later but it's definitely the best option IMO, the block option is a good one too if you really care about hiding those. Found this one https://www.printables.com/model/330707-simple-dry-erase-board-mount on printables that's more of a hook type mount, but yeah, something in that could work too.

I assume 3M makes those inserts for their hooks because it’s difficult to mass-produce cheap hollow objects with a firm flat back.
We don’t have that problem.
I have stuck all manner of things to the wall with command strips — power strips, 3D-printed hooks, boxes.. whatever has a flat back works fine.
