ZFS properties that can't be changed after pool creation

I asked this a couple months ago on reddit, and compiled some useful info for folks new to ZFS. Including here too for discoverability.

For example, ashift=12 can’t be modified after creating your pool. What are all the other properties like this, that you need to make sure you get right when creating your pool and/or datasets, and can’t be changed later?
