Not to be facetious, but perhaps you should consider correspondence games. In the realm of live games, the preferences are very personal, so it is hard to answer. I prefer byo-yomi, because until the last period the stakes are not so high if you slip up, as seems to have happened in one, if not all three, of your simple-time games. I think most people play a short byo-yomi like 30s just to have a quicker game. If that is not a consideration, then you could try something like 45 min main time and 5 x 1 min byo-yomi (my preferred setting for a serious game). By the way, if you ever play a bot that doesn’t ponder, then you will have only about half of your normal thinking time. Also, you might want to practice with some unranked blitz games. Afterwards, an increase in time will seem luxurious.
