Many people buy the smallest version of this for their first Stream Deck, thinking its much bigger than it is. I suggest the 15 key Elgato Stream deck to start. The price isnt terrible, and you DO have the room for this! This will help you switch through you scenes a lot quicker, it can play sounds for you, as well as activate voice changer apps and MANY other things.

Advice to new streamers - GET A CAMERA. I know you probably have issues with showing your face on stream but it will definitly be a game changer for you. You really don't have to show your face, but maybe even hands on keyboard and mouse or controller can be showcased. This is the webcam I started out with. If you pair it with decent lighting (see the ring light also suggested in this collection) it will do wonders for you and will be plenty good enough to start with.

Lighting is important for streamers just getting started. A decent light can make even a low end webcam look a TON better. Trust me. This is a very afforable option for beginners, but I still use mine. I have two different lights I use in front of me. Two will help as you don't want it directly in front of your face. I prefer the cool white option.
