Good evening, fixing up my garage in a 45 year old house and the garage slab has settled and shrank a bit. What product would be recommended to fill a gap between the foundation and the garage floor slab. Max gap is about ¼ inch.

Couldn’t have said it any better. Spot onSika self leveling sealant. You should put backer rod in the cracks first if they're deep or the Sika will just drain out.

I'll just toss out concrete caulk in gray. Plus 1 on backer rod down at least the width. When I do this I use tape on both sides of the crack. Good tape sticks to concrete with some pressure. Sometimes I use a mallet and a folded rag to set the tape. If that doesn't work, duct tape will. That's what I use on bricks.
