Do you need to pay separately for iPhone and iPad when upgrading the device?

If both your iPad and iPhone are signed-in to iCloud with the same AppleID, your additional “paid” iCloud+ storage is available to all devices that share the same AppleID.

Could you please explain in more detail? Are you planning on purchasing new devices?

iOS/iPadOS system software updates cost nothing at all - for the entire life of the device.

The storage is tied to your Apple ID / iCloud account, not a specific device.
