For context, we live in a 450 sq ft apartment
Take this with a grain of salt because I didn't have the space constraint you have. What I did find true is that all the advice on registry items was helpful to a point but your baby and your needs will be unique so don't feel afraid to try stuff or get rid of stuff that is recommended.
For changing station -- as long as you have some sort of pad, you can just have it on the dresser. We had a silicone changing pad that was shaped like a peanut but I'm unsure of the brand. It was easy to clean since it was silicone and you could just wipe it down with a clorox wipe if there were any spills.
For reclining couch versus glider chair -- I really like the gliders that swivel. Not every baby will want to be rocked, a lot of the times they actually like being swayed. Having the full range of motion was nice -- and some of the glider chairs can have an ottomon to prop your feet up and be in more of a lounge position.
For stroller, having a stroller that connects to the car seat is super nice. My baby is 7 months old now and we still use the stroller that has a carseat attachment. She's about to outgrow it but it's come in handy. With that said -- we didn't really go out of the house a ton until she was 3 months old.
The first few months, they truly do eat, sleep, poop, eat, sleep, poop, in endless cycles and their awake/alert time isn't very long.
