Concrete Crack Repair (Garage & Driveway Options)

Have developed a crack in garage floor slab which extends external to the garage into the driveway. I think it’s due to localised subsidence in that area because of a reduction on ground water over that last few years (long story). I do not believe the crack will continue to open but I would like an expert opinion on that and options ranging from a basic repair of the garage crack only up to a full repair of the garage slab (if required) and replacement of some or all cracked sections of the driveway with new concrete. I do not believe it’s structural but pending opinions on the crack I am also considering diamond grinding and epoxy coating (epotread 1000 or similar) the garage floor as well. I am not in a hurry to get this done and the scope of work done I’ll be determined by budget rather than timeframe. Happy to upload more photos or answer questions as required. Cheers
