Ctek battery maintainers: Useful when installing new?

I’m wanting to install a new battery while maintaining all the computer settings/memory items. I’ve got a Ctek battery maintainer. Here’s what I’m thinking I can do (shown with the old battery)—will this work? If so, what setting should I use? (The regular automobile setting, or something short of that, ie the motorcycle setting?) Other than the obvious when working with car batteries (ie don’t short out the positive onto the car chassis or the neg post), anything I have to watch out for/avoid doing using this technique? TIA.

Full disclosure: this is on a 2019 Subi Forester.
