Correct my Japanese please.

私は　このような様々な本格的な食べ物と文化を体験などの利点を得る　と　思います。
I think I will gain advantages such as experiencing different authentic food and cultures.

（私は）様々な本格的な食べ物や文化を経験する（といった）利点を得ると思います。

様々な本格的な食べ物や文化を経験する利点を得ると（私は）思います。（or 利点がある）

●No spaces are needed.

●If you want to emphasize your own opinion, you can put ”私は”. There are two possible positions.

●"このような" would refer to something which appears before this sentence. If you refer to it, you can leave "このような". 

●”体験” vs. "経験"

Both means "experience". "体験" is used for ONE memorial experience. "経験" is used for more wide and various experience. I guess in this case "経験" would be more appropriate.

How do I say "As well as meeting new people which who will help me with the language."

言葉を助けてくれる新しい人たちと出会うことと同じく

言葉を助けてくれる新たな人たちと出会うことはもちろんのこと

c.f. 

Through meeting new people who will help me improve my language.

私が言葉を上達できるように手伝ってくれる新しい人たちと出会うことを通して

Combining your two sentences,

I think I will gain advantages such as experiencing different authentic food and cultures as well as meeting new people who will help me with the language.

言葉を助けてくれる新しい人たちと出会うことはもちろんのこと、様々な本格的な食べ物や文化を経験する利点を得ると私は思います。

Change the above sentence referring to my comments.

I just modified your Japanese and directly translated your English.

I would also say;

言葉を助けてくれる人たちと出会うことに加えて、彼らの様々な食事、文化などを経験できる利点があると私は思います。

Please help me! Thank you :))))
