I honestly feel that the "trash fights" are sorely lacking in BG3. Sometimes it is nice to have fights that are fairly easy and make your characters feel powerful. As for day/night cycles, I feel that is mostly based on the story being told. Perhaps there are segments in the game later on where there are night missions?
Trash battles are the worst way to waste a player's time. They are neither interesting nor demanding in any way. I definitely prefer situations in which every fight is at least a medium challenge.
