They’re all pretty much the same seats regardless of aircraft.
The only way in and out of the seats is by the feet at the aisle.
For a couple you’re probably best one behind another, but it’s still not very conducive to talking. That said, the ottoman doubles as a (not very comfortable) buddy seat so you can sit facing one another and chat for a bit. Similar to the CX F seat. You may be able to dine together, but it would probably be tight on the tray table (CX has an extension when you do this).
