Ime there are two types of soundstage depth.
The first type would be a deep-soundstage "they are here" presentation. A "they are here" presentation is an approximation of the musicians playing in your acoustic space. Minimizing the reflections off the wall behind the speakers, either by distance from the wall or acoustic treatment on the wall or both, along with minimzing the first same-side-wall reflections, contribute to a deep "they are here" soundstage. The soundstage depth is still somewhat constrained by the room, BUT is can be much deeper than if no attention is paid to these early reflections.
The second type would be a "you are there" presentation, wherein the venue spatial cues on the recording are perceptually dominant over the "small room signature" cues of the playback room. So the sense of space (including the soundstage depth) varies from one recording to the next, corresponding with the venue spatial cues on the recording, whether they be real or engineered or both, and is not constrained by the room’s dimensions.
Imo the second type is the more enjoyable and the more elusive, and I can go into a bit more detail about it if you’d like.
I’m not saying that favorable room interaction is the ONLY contributor to good soundstage depth, but ime it is one of them. Another factor is, the loudspeakers themselves should free from strong edge diffraction, as that can degrade the image localization cues, including depth.
