Use 3D modeling to create a bedroom

Hi guys, I wanted to make a 3d model of my room to know exactly how it would look before starting to buy stuff that I would not be sure to like. I have a gaming setup also at the same time, so I wanted to implement, for example, monitors and try different type of desks and see how it would look in my room, if it will take too much space or not. It is my first time here, so I was looking to get some help concerning 3d modeling, also if there is any software that are more intuitive than others to begin with. Any type of advice would really be appreciated
