Based on research findings, the friendliest hamster breeds are primarily those with docile, people-friendly personalities, making them ideal for novice owners. Here are specific recommendations:

Campbell's Dwarf Hamster (Wild Color/Lilac)
Temperament: Gentle and timid, rarely biting, and easy to build trust with their owners.
Traits: Highly adaptable, low-maintenance, lively yet interactive—perfect for first-time hamster keepers.
Pudding Hamster
Temperament: Lazy and docile with a slow reaction time, rarely showing aggressive behavior, and maintaining stable interaction.
Note: Prone to obesity, so diet control and adequate exercise space are necessary.
Silver Fox Hamster
Temperament: Highly affectionate and relatively intelligent; can learn simple tricks through training and enjoys interacting with owners.
Traits: Has a beautiful white coat but has a weaker constitution, requiring careful care.
Golden Hamster (Syrian Hamster)
Temperament: Larger in size but gentle in nature. It has a strong sense of territory (needs to be kept alone) and is suitable for families willing to invest patience in building a bond.
Lilac Hamster
Temperament: Calmer and gentler than regular Campbell's dwarf hamsters, making it a good fit for owners who prefer low-interaction pets.
General Recommendations
Best for beginners: Campbell's dwarf hamsters (wild color or lilac) or Pudding hamsters, thanks to their stable temperament and easy care.
For high interaction needs: Silver Fox hamsters or Golden hamsters, though they require more time for training and care.
(Note: Individual personalities may be influenced by the living environment and the owner’s interaction style; the above reflects common breed characteristics.)
