Try adaptive wide angle and lens filter in photoshop or in lightroom under geometry try upright/guided first tho try everything. None of these are perfect but since you already have a lifetime experience looking at rooms you can eye ball it using a known object as reference.probably not the most technical explanation but it’s gonna get you to “good enough” within five minutes, from there on you decide if it’s mission accomplished or the rabbit hole😁
