It sounds like you have several concerns:
the need to build self-awareness
the need to improve communication and self advocacy skills (Has the school done an AAC evaluation and does she have an AAC device, if needed?)
concerns with her placement setting not having enough exposure to typically developing peers (concerns regarding placement/ least restrictive environment)
I would recommend writing a letter of parent concerns and requesting another meeting with your IEP team if you haven't recently discussed these concerns. If you have recently discussed the concerns, see what the district wrote in the PWN regarding your concerns, and then consider your procedural safeguard options.
You listed that your daughter is with peers for art and gym. Could the school include her with peers for music, library time, recess, lunch, etc? If they say no, you can ask for an explanation in PWN.
Are you able to help her be involved in community activities outside school (Scouts, religious organizations, 4-H, sports, etc.)? Does she like to do community outings with you (grocery shopping, going to the library, museums, etc.)? All those things give children community involvement outside of school.
Out of district placements are a more "restrictive" setting on the continuum of placement options. It's really an IEP team decision as to what's the most appropriate educational setting for a child. If you disagree with the placement the district chooses, then you consider your procedural safeguards.
