This trim jump changes the engine from 2.5L I4 to 2.5L I4 Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the 2.5 S Carbon Edition if the 2.5L I4 already feels sufficient for the way you drive. Step up to the 2.5 Carbon Turbo only when the 2.5L I4 Turbo powertrain is the reason you are moving higher in the lineup.
