Garage floor/apron repair

Garage floor/apron repair
We recently had a mudjacker bring the apron back up as it had settled somewhat, presumably due to water ingress at the apron/floor joint. He strongly urged me to follow up by filling that gap, as well as the floor control joints with self-leveling polyurethane caulk to prevent future water entry, which I am doing now. I have eliminated the waterfall off the eave by redirecting roof runoff via rain gutters... that helps a lot.
For the small random cracks (1st photo) he suggested I use a thinner-bodied material; my local home improvement store has this in quart size squeeze bottles, but it is not polyurethane. Would this stuff be appropriate or would the urethane caulk be better for these as well?
What should I use to repair the large chips/spalling (1st & 2nd photos) caused by salt/freeze/thaw... some sort of mortar mix, vinyl patch, or other?
I tentatively plan to implement some sort of floor sealant in the future, so any fillers, other than what I'm using in the control joints would need to be compatible with that.
How shall I repair the broken part of the apron seen in the 3rd photo? Those broken pieces are only about 2" thick. That surprises me: I was expecting more thickness there, but then again, I'm far from an expert.

Ace sells a product which is nothing more than Portland with sand. It's called Topping something. Chop out what's loose first & widen the crack. I also recommend to mix it with a bonding agent. It looks like a gallon of milk & you mix it with the dry mix.

For those small cracks do not use a cement based patch it will just crack again.
Clean the crack and use Sika self leveling sealer, it will provide flexibility when, not if, the crack shifts.
