For my 992 with LiPo you would want this specific CTEK charger. They do make one 7002 (IIRC) which you can switch modes and do either AGM or LiPo. But this one is specific for just the LiPo.

I have had great results with the Battery Tender that has the ability to charge all types of batteries. I have 3 of them.

The dual mode trickle chargers, if you have a power outage, the charger will go into "neutral" meaning, you would have to select the battery type to resume charging (AGM or LiPo). With the individual purpose trickle chargers if the power goes out, it will resume as it is specific purpose and no selection needed.
So I like the individual ones, so they can be unattended...

All of them will have a cigarette 9v port (the 992 is passenger side footwell).
I think the best way though is to get a permanent pigtail (direct to battery) - easy quick connector (you can get a charger from Ctek on Amazon, and get 2 Ctek pigtails (one comes with the CTEK. Make sure you get an AGM (or lithium charger - depending on what you have) - assume all of yours is AGM battery type.
All my cars have the pigtail attached, makes it easy to connect/disconnect the charger.

You can also get a two-pack of microprocessor battery charger/maintainers from Costco, Duracell brand, for $80 that will also work fine. They include the pigtails. I run my pigtail just out the upper trim panel in the trunk and charge with the front hood just set down on the latch.
No issues in a year.
There seem to be as many charger threads on this forum as oil threads.

I imagine that most cars sit for a while during transport to Emden, or at the port, or while on a ship to their next destination. Sometimes this is for 3-4 weeks. It seems logical that none of those cars are on chargers.
And yet it would seem also unlikely that there are a high percentage of cars that drain their batteries during that time?

This has been mentioned countless times.
Whatever you believe is right is what you should do re. trickle charger or not. To debate endlessly as to its usefulness is what is it is. Unlikely or not, the manual clearly recommends so many miles per month etc. and if not place on a charger. YMMV

As stated above, 
I don't see AGM selected as I don't see the light on and assume you don't have a lithium battery. It should eventually go to number 7 and 8 if you selected recondition.

CTEK with connected pigtails for quick connect/disconnect. As with AGM and especially LiFePO4 batteries do not leave the batteries permanently connected. These batteries need to be able to discharge and then be recharged and as Richard mentioned get the specific charger for your type of battery.
I've got 3 chargers. A regular wet battery one for my Touareg and Olga (my skid steer), a CTEK AGM for the wife's Macan and a LiFePO4 for my 992. The right tool for the right job

Am I missing something about keeping the battery permanently connected? I was under the assumption that if you had the correct CTEK charger for your battery type you could just keep it connected while the car is in storage. I thought the charger would go into a maintenance mode and just charge the battery after it discharged a small amount and then repeat.

Well the jury is still out on that. Personally I don't feel that a battery (irrespective of the type) should be connected (trickle or not) permanently. IMHO it needs to be able to discharge to be able to recharge fully. I tend to leave it connected if I'm not driving my car for over 4 days, after that I don't connect it (assuming a good 40 mile drive - I'm 20 miles from town) for another few days. That's just my take on it and I apply that to Olga (my skid steer), my Touareg where I triple the length as I don't have all the gizmos and the wife's 2020 Macan S

First you need to determine what kind of battery you have. What you show is for a wet cell battery. If you have a gel AGM then you need to select that kind. If you have a Lithium one you have the wrong charger. Float will be fine, with my humble opinion above caveats.
