(I haven't used these much so I'm not sure how useful I'll be, this is probably a question for the more advanced users, but I'll try)
The built-in multiplayer plugin is definitely better for turn-based games or games that don't suffer from latency, because it will always have some sort of latency no matter what, which can suck for competitive games like you described. I don't know much about photon or node.js, so i won't say anything about that.
As for those exporting options, consoles require third-party services to transfer the game to consoles (such as Chowdren). I think you can export to steam (I think using NW.js, i may be wrong), but I have no idea about steam deck. Exporting to mobile is an easy option, too. Construct is great at exporting for mobile.
