The only ones I would check next would be
UNIT_QUEST_LOG_CHANGED -
https://warcraft.wiki.gg/wiki/UNIT_QUEST_LOG_CHANGED
And then ...
TASK_PROGRESS_UPDATE -
https://warcraft.wiki.gg/wiki/TASK_PROGRESS_UPDATE
QUEST_LOG_UPDATE -
https://warcraft.wiki.gg/wiki/QUEST_LOG_UPDATE
Otherwise I would use the /etrace command to see what events trigger soon after you log in
