I would grade the outside and then gravel the inside to keep water from sitting and possibly causing uneven frost heave.
For the pitting (honeycomb) I would parge or sack the wall depending on the finish you after.
Coatings or sealers could make it hard to parge or sack later on but all...
If you plan on doing a floor covering depending on the desired slope a topical patch could also be used pretty easy mix in a bucket and trowel out from about 1/16" up to a max of 1 1/2".
If you are parking in the garage with snow covered vehicles you should have about 3-4" of slope going back...
