What is the best backend for voice only social media platform on iOS?

I am looking to build an iOS application that will be a voice-only social media platform. Very simple concept. Will need push notifications, user management among other features that go with social media. I know there are the top 5 backends (Back4App, CloudKit, Parse, Firebase, and Amplify) but I'm not sure which one is the best for my app. Furthermore, I have a Linode account and want to host the app (data, etc) on my own server. Any suggestions would be helpful!
