You likely have long term success at the steps and repointing the bricks, the foundation less so without determining the extent or how deep the crack. Does the home have a basement?

One benefit of a good mason is they should be more skilled with matching mortar and I'd get a quote before starting.

No basement, just a crawl space, of which I can access albeit kind of a sketchy crawl to that section...I redid some plumbing a couple of years ago and did not see it cracking to the other side.

I see no indication at all of anything sinking. That's good news on a 100 year old house.

There is no sinking or water issues, no framing issues. I just need/want to seal the crack and fill in the worn away concrete. My fireplace/chimney, is another story haha, that will need a structural person, mason.
