Do these have useful items or class options like the adventure paths in them?
The short answer is generally no. These $5 scenarios are just short adventures and they won't come with any classes/spells/etc like the APs do.
They do sometimes come with Boons, though. Boons are small little things your character gets for completing a scenario or meeting certain objectives. They are mostly designed to interact with Organized Play, but a few of them could potentially be relevant in a home game.
An example of a Boon might be a contact or ally that would grant you some benefit in a different scenario, or a black market contact that gives you a discount on a piece of equipment.
