Submitting only to the ecumenical councils and only to other teachings that resonate with one’s conscience?

I think it’s fair to expect an orthodox person to submit to the seven ecumenical councils. Beyond that, there seems too much either split decisions or things that could change. I asked on here, how much submission to one’s priest was required and there was split ideas on that. Some say it’s not like the orthodox sit around worrying about submitting to the priest or the priest worrying about getting submitted to. While others say submission is necessary at least on open questions. In another thread I asked if there was anything like the extraordinary and ordinary magisterium from catholcism in orthodoxy, which means formal teachings to be submitted to, and informal teachings to be submitted to. The responses said it’s not like there’s an exhaustive list but that it works sort of like that.The issue seems to be that each orthodox seems to figure out for themselves what’s expected of course with the guidance of priests but still ulrltimately on one’s own. Somewhat like each is somewhat winging it. Take contraceptives or remarriage or emerging or even classical bioethics or ethics in general, and a lot of religious p​eople think this or that must be submitted while other people say otherwise. Or that the holy spirit is guiding the church this way or that way. I’d consider joining orthodoxy but the authority and submission expectations seem arbitrary and stifling to one’s conscience especially when a teaching turned put mistaken to begin with
