I don't want to completely refute this because I'm also an amateur and there are a lot of instabilities of consensus, but Baal was at least also the son of El in Canaanite religion which predated an Israeli kingdom.

My understanding is more that Yahvists had more nomadic origins and populated (/conquered, possibly the Levites[1]) a Canaanite cultural context and then there was religious syncreticism and interest in merging them. Depending on the specific passage's history there's either a ret-coning of "all one god" or at least the interpretation that way (including how your links translate those passages).
