One thing is being aware of bad actors on the internet, in that case IOS could be an option, other thing is being aware of the mass surveillance and manipulation across the digital space, and that's the thing we're more worried about in communities like this, in such case, IOS is no better than shooting yourself.
You can't become privacy conscious without sacrificing something, some friend will go away calling you a paranoid, somo products you own will become garbage, that's just normal here.
If your using GrapheneOS you don't need 2 devices, you can setup diferent profiles/users in the settings that are containerized and don't interact with each other. Your main profile will be completely foss and degoogled and in the second one you can install the play services from the GrapheneOS app updater (if you already have them in main i recommended you to backup and factory reset to make a clean install). There you can have Google Maps and all the spyware you need, you can even set it up so you recive notification from the second profile in the main one.
I can already picture it
"you don't want to open a government backdoor? No more tax money for you"
"your foss project needs to be verified by the government to be selectable for founding, you don't want to? Well, no tax money for you"
"For your foss project to be created we need to verify it now that by law all foss projects receive tax money, you don't want? Delete everything"
And this is how you will own nothing and will be "happy". You can't escape the surveillance by using foss, go live in the woods before it's to late, and don't forget to carry your tin foil hat, be safe.

Obsidian is not FOSS, I still use it because I find it to be the most complete note taking app. You can download it from the Aurora Store and disable the network permission, same on linux downloading it from Flathub and disable the network permission using Flatseal
Do you actually trust Apple? Do you really not see it as a honeypot? Are you sure Apple don't track you and respect your privacy as a human being insted of seeing you as a profitable product? Are you out of your mind?
