It depends on whether you live in a house or an apartment and what your financial capabilities are. I live in a house with a yard and I have a Labrador, 5 years old. Do not take from a pet store, but rather from a kennel or ads for puppies in need of a home. So, if you see an ad, you will be able to talk to the owner. The puppies will have been with him for at least 2 months and he will know more or less their character, he will be able to recommend you which one to choose, etc. Otherwise, I do not recommend a pug from the breeds you have listed, because there are many respiratory problems, and it's up to you whether you want a small or large breed, a guard dog or a pet.

All breeds are like GMOs, invented by man to be bought, therefore - to die faster. They ALWAYS have diseases. In principle, all humans and animals have diseases, but purebreds are less likely to live long. Are there few dogs in the shelters? Do you want a purebred dog to brag to your friends and take off chicks, like it's a new car? The animals have to choose for you, not to buy a brand of saltines from the store.
