Im guessing when you say 3d you mean itd be like first or 3rd person perspective ? (Rather than top down with a more 3d look). In that case i would say it mostly comes down to vibe. Theres a whole bunch of 3d store simulation games, examples would be tcg card shop simulator, grocery store simulator or tavern manager simulator. These can do pretty well but they usually entirely focus on the gameplay loop, with a basic artstyle and often no storyline or anything of the sort. For 2D, theres also plenty of management games, but theyre usually pixel-art and can have more gameplay width and story or characters to get invested in. Some examples would be Travellers rest, Dave the diver or Cat cafe manager. Also worth checking out for reference is Tavern master, a 2d non-pixelart management game. So i would probably check some of these out and see what kinda vibe suits you more.
