I think in all Europe now the cars are mostly *either* superminis or SUVs, but superminis have bloated in recent years - for instance a former work colleague got a new VW Polo recently, this is now same size as my Mk 7,5 Golf GTI. Fiat 500 has similarly grown, at least the new ones are electric.
I have never wanted an SUV - but I am a single man and don't have kids or dogs.
I think one factor is end of "nuclear family" and a lot of people having multigenerational extended family groups with biological kids and stepchildren, with a wide age gap of kids living at home and depending on parents for transport (from primary school kids to teenagers) and an expectation of more interior space in a family car (compared to 30+ years ago)
