I feel that GrapheneOS is a good compromise. It's significantly more private than an iPhone and after 2 years of using it I really don't feel like I'm missing out on anything.
Couple that with a Nextcloud instance, and you are golden. This private cloud is where you can synchronize your contacts, calendar, photos, files, bookmarks, passwords, location, news, podcasts, music, tasks, notes and host chats and video calls.
To mitigate telco surveillance, switch your number to VOIP and use burner SIM's or pretty good phone privacy.
