But there is no easy service you can buy to start monitoring cameras and microphones.
In general it's more secure than Android.
On iOS, you can't disable security at all (yay freedom), but you can just jailbreak the phone and install whatever you want. If the attacker has physical access to the phone, security on both platforms is comparable, i.e. zero.
On top of that there is no such thing as an unteathered jailbreak for iOS 10. The best you can hope for is a semi teathered jailbreak which requires you to manually run an app every time your phone restarts.
Also doing all those steps you mention are meaningless is many cases because an attacker close to you (think bitter divorce or corrupt business colleague) can just grab your phone for a minute and your goose is cooked.
