The correction:

یک چیزی درباره ی خودتان به فارسی برای من بگویید.

yek chizi darbaareye khodetaan be farsi baraaye man begooyid.

می گوید is the present progressive verb for third person singular and is not compatible with شما which is the pronoun for second person plural. The compatible verb is می گویید which can't be used here. The imperative form of می گویید is بگویید.

را usually comes after an object, so you can't use it after من.

پیرامون is more formal than درباره, so people often use درباره.
