Zombies can break doors on normal, and also break wood based blocks, leaves and glass and maybe some other blocks
Actually what if on easy they can break doors, normal some block and hard all breakable blocks, idk.
Oh and zombie villagers always have a 100% convert chance and the difficulty only makes dezombifcation take longer and maybe require enchanted golden apple on hard idk.
