Real talk: Star Trek, but like specifically TNG/DS9/VOY era Trek. I love those shows but like if we're talking about realities where I could feel as realistically comfortable and free to exist on my own terms, see things I would never have imagined I could see otherwise and be safe and secure doing so, Trek is the one. Ideally i'd need to find my way to a Federation planet and then claim citizenship or at the very least rely on their infinite hospitality, and then after that i'd probably divide my time between devouring as much about idk, non-human religious iconography and fiction as I wanted, eating wildly indulgent but nutrient-adjusted replicator feasts and painting/building a monster garage kit/painting subculture in the 24th century with members from multiple planets. Maybe there are more "Exciting" settings to visit but it's a tough ask not to pick "The infinite resources luxury space communist reality" if offered lol
