I would first reflect on what gets you "hooked" to the point you feel guilty. For me, League of Legends was VERY addictive. My mood for the evening would change depending on how much I won or lost and I always wanted to queue up for "just one more game" even if I had another commitment in 30-45 minutes. So for me, dropping online team-based competitive gaming was the right move. I would look into games that let you start/stop whenever without any issues. These fit best into (I presume) your adult life, without having the classic "I can't pause this right now" moments. I recommend Stardew Valley if you want something very laid back (and it works on nearly every system) and then one-player games like Horizon Zero Dawn, Witcher 3, Portal if you want some story, puzzle, action. Each is award-winning and has deep gameplay but also easy enough to approach (if you have a background in gaming as you mentioned).
