Default Need help for product selection and preparation

See attached photos for what I'm trying to patch up (the gaps appears to be too big to be fixed by a crack sealant economically).

The selection is quite overwhelming. Which of the following product would you recommend using?

(7) none of the above; other

In addition, in order to properly patch over these cracks, do I need to remove the top part of the old concrete patch (using a chisel or jackhammer), or can I apply the patching material directly on top of the old patch after removing all the dirt?

Thanks in advance for your help.

If those are the control joints, i would recommend the self leveling concrete caulk. I would do the same where the sidewalk meets the stairs. Any concrete product is not flexible and will likely just crack again.

Clean the joints and use a polyurethane caulk;

typically apron/vest stores only carry the 'ns' version (non-sag/vertical) which means you'll need to 'tool' the mtl against the sidewalls,,, teaspoon & wtr work fine,,, pay attn to jnt depth:width ratio per mfg's instructions,,, be certain sidewalls are CLEAN,,, IF you can find the 'sl' (self-leveling) version, no tooling rqd,,, you'll need backer rod - either open or closed cell works fine
pro mtls + tools + methods + knowledge + skills = pro results
