Weirdly in this case I think I agree. You can look at my previous comments about how much I hate Apple but it seems to me that OP isn’t too technical and installing a custom ROM might not be what they’re after. iPhones don’t have any of those annoying games and stuff preinstalled, as long as the carrier doesn’t install stuff. I’d suggest a refurbished unlocked iPhone though, to save some money. Make sure the previous owners account is removed from the device or else it’ll probably just be a paper weight.
If OP is open to custom ROMs then GrapheneOS is a great choice but LineageOS and DivestOS are also great options for someone that wants to get started with privacy and they support a lot more devices, that can be got for cheaper than an iPhone/Pixel. Again, I’d recommended a refurbished, carrier unlocked phone that is supported by one of these projects
