I am a victim of the network effect who wishes to degoogle. What do I do?

This post is going to be a bit personal (and maybe a little bit out of context, it's not just Google software I want to remove) but I'm tired of not knowing what to do about it. I want and have wanted to get rid of a bunch of proprietary software in my life, including but not limited to Google's software, for quite a while now, and I even got a Pixel 7A with hopes of installing GrapheneOS. But there are a few problems. First, my parents are understandably concerned and need me to use Google Maps' location sharing whenever I go to school. All my classmates use Instagram and we have that as our only messaging platform. I currently use DFInstagram, but I feel that it is not free from spyware. Finally, I also own a DJI Mini 3 Pro, and the associated DJI Fly app just refuses to work under GrapheneOS (I tested). Is there anything I can do to replace or limit the access of these aforementioned proprietary apps?
