I have always daydreamed about being a hobbit!
I agree that hobbit culture is very Fe-Si. I guess I imagine hobbits as ISFJs more but I can see ESFJ hobbits as well.
Looks like it could depend on the hobbit:
Provider (ESFJ) — Bilbo
Keirsey calls providers “the most sociable of all Guardians” and says they are “friendly, outgoing, [and] neighborly” to the point that they become “restless when isolated from people.” He also adds that they are careful to remember birthdays. Starting to sound like a hobbit?
An ESFJ’s primary function is Extroverted Feeling (Fe). This makes them quick to express their opinions and judgements, though they like to do this in a way that maintains peaceful social functions. Note how Bilbo responds to the arrival of all the dwarves — he is not shy about letting them know what he thinks about their unexpected arrival, yet he still plays the perfect host. Like other types with Si as an auxiliary function, ESFJs can become set in their ways and comfortable with routine (which is what makes him appear introverted when he is upset about being disturbed by company).
Protector (ISFJ) — Sam
Not many fictional characters are as easy to type as Samwise Gamge. He is the perfect ISFJ. Like the ISTJ, an ISFJ’s primary function is Si and they tend to resist change and be comfortable with traditional ways of doing things. They tend to settle down and be comfortable with routine (Sam never considered leaving The Shire until Frodo went on his quest). With Fe as an auxiliary function, ISFJs are very people-oriented and attuned to the needs of others, especially their close friends. They have a strong sense of responsibility and loyalty, and readily serve others — “Come on, Mr. Frodo. I can’t carry it for you… but I can carry you!”

I've always related somewhat to Eowyn but this might be just wishful thinking on my part.
Personally living in the shire would make me claustrophobic but I might have trouble leaving the safety of my home towards new adventures too, so I think Bilbo is a good compromise between both (what with the help of Gandalf pushing him to leave.)
