I like the T-34 layout[0] - I like how much 'science' (research) did he put in it. An another one is the callum layout[1].
There is an option with QMK to rediscover TRRS cable when it gets disconnected or is plugged after startup, but I see now that that's not the only problem. TRRS is an easy/cheap solution, but a dangerous one if not correct.
