Poodle is a great choice for a family dog, but on a farm, you have to keep them groomed very short, or they will carry all kinds of burrs in their hair, some that are very hard to get out.
Their grooming requirements are not every one’s cup of tea, best monthly and daily brushing if one is an outdoor dog.
We had some, I groomed them, wonderful dogs, but you have to be a poodle person to really enjoy them and not everyone is that.
As for dobies, rotties, pitties, any breed that is currently in the “perception of dangerous dogs”, I would think hard if I wanted to live with the liability that brings.
We had dobies and one rottie in the 80’s, as obedience and nursing home therapy dogs and I can say, there were people that just flat were so scared of them, they quit coming around to visit and told us, those dogs scared them silly, even at their best.
Someone with a farm and family should consider that aspect of those breeds before acquiring one.
