iCloud Question

[Apple_Glen_UK]

Please forgive my ignorance but I don't know a lot when it comes to iCloud. I have a MacBook Pro and an iPhone SE. I don't use iCloud and prefer to store photos, music and documents on my Mac. I don't use iMessage and I do my own back ups. Therefore, is there any point in staying signed in to my Apple ID on my iPhone? I don't want to log it out and then encounter problems.

If you don't stay logged in, you won't have access to your Apple mail, or be able to install/update apps.

It also won't be part of Find My iPhone, or subject to Activation Lock if stolen.

be able to install/update apps.

This one... not necessarily. You can sign in to different accounts for iCloud and for iTunes/App Store. So OP could sign out of iCloud but remain signed in to the App Store.
