Just moved into my first apartment (350 sq ft studio), looking for some ideas!

I just moved in to my very first apartment and it's a small studio space. Here are some pictures. I have my bed and I feel like the kitchen and bathroom are complete, but I have no idea how to get the most out of the living/bedroom space.

Ideally I'd like to have some sort of media unit for the TV and consoles, but I'd also like to have a small desk somewhere for a computer, maybe some shelving units for books and other little things (for example I was thinking maybe a horizontal Ikea Kallax unit for the TV and using the cubes in it for storage)

What kind of furniture should I be looking at to maximize space and storage? I feel like everything in here needs to have a purpose so I've been a little hesitant about buying furniture without making sure it fits. The bed takes up a lot of space so I'm not sure how to go about putting a sofa in there too. I'd appreciate any insight :)

Thanks!
