But a golden doodle is not a labradoodle.
A golden doodle is a poodle x golden retriever
A labradoodle is a poodle x Labrador.
It is impossible to predict which traits each puppy in a litter will inherit from the parents, so predicting a set of behaviour patterns from what is essentially a mongrel will not work well.
Out of a litter of 11 dogs, which are just a year old now, each one has inherited and developed an absolutely different character to their parents. Each has a bit of Mum and Dad, and a bit of each of the grandparents BUT in very different proportions.
Labradors have very different temperaments depending on their breeding, I expect poodles do too, so a cross of them both will be even more unpredictable.
Sorry to sound negative, but I really don't think it's easy or even possible to predict with any certainty which characteristics are going to be dominant in a cross breed. People have spent years trying to refine behaviour characteristics in many breeds of working dogs and are often thrown a curve ball. What should give the best possible working dog on paper, in practice isn't quite as expected.
