I honestly don’t think you’d get that much variation. Beyond phone/sms, the list would likely end up with just these:

- decent camera

- messaging apps (WhatsApp/telegram/signal/etc)

- email

- maps

- rideshare (uber/lyft)

- mobile wallet (tap to pay)

People will also demand a browser, but that kind of defeats the purpose. All the apps should be utilities that you can’t spend hours in.

I suspect people would also demand music streaming, but I’m not sure really why you need that.
