The Apollo program had a big impact on the development of integrated circuits, turning software engineering into a real discipline, and fly-by-wire technology. Could this have happened without? Probably yes, these technologies aready somewhat existed, but the program pushed them much harder than they would have done otherwise. Same thing for later space missions, they pushed technology to the limits of the time.
A good example here is solar panels. They were invented before the space race, but for what, why do you need them on earth? We had cheap oil and fossil fuels, nobody cared about renewables. But for the first 50 years after they were invented satellites was what kept them alive, as it made sense to use that technology there. That gave them a real use case, which continued investment and development into them.
I doubt today we would have the same level of satellite technology today if the space race didn't happen, so it's unlikely we would have the same level of solar panels either.
