I think a great drama for you to look into is "Meet Yourself." The female lead is mature, thoughtful, and well-written. She and the ML work very well together and are such green flags in terms of a realistic, healthy relationship in my opinion.
FL is really strong and smart. She is really good at Archery as you can see if you watch the drama. ML is weak but he is smart and teaches FL stuff in later episodes that will be useful in early episodes. Their relationship isn't toxic at all and both of them love each other even though they do not kiss each other. The drama is in reverse timeline so when FL first meet ML he doesn't know her and vice versa.
I'm not sure if my suggestions will fulfill your expectations, but I enjoy legally romance, sword snow stride, here we meet again, double love, and others.
I'm pleased see some of my faves already mentioned, Le Coup de Foudre and Hidden Love but here's another you may want to check out. Very grown up and realistic, and I raved about it here:
Flight to You - FL is a headstrong pilot. ML is an experienced commercial pilot and a stickler for rules. So their miscommunications revolve around that. Otherwise he is caring.
I'm not sure if my suggestions will fulfill your expectations, but I enjoy legally romance, sword snow stride, here we meet again, double love, and others.
I second so many others already mentioned here, but I'm currently watching You Are Desire and it is just wonderful. Strong leads and almost none of the tropes.
