I live in Barcelona city but I have no kids. I often see whole school classes on the metro though, going on school trips. I think the metro is just fine for them. Also, walking everywhere is really feasible. I stopped using the metro for everything due to Corona. Though I picked it up again after getting the vaccine, I still retained the habit of walking. Barcelona is nice and compact, I can walk everywhere within an hour or so. Not sure about Madrid, I've only visited. If I had a car I wouldn't even know where to leave it to be honest. In my area there's no parking available except some highly expensive garages.
