You will quickly discover the main appeal of 3h is the monastery because maps are super cheesed by warp, stride battalion, Retribution battalion, bow knights, etc so the actual meat of the game is not a large part of your play time. There are so many tools that make maps go faster and they arent hard to unlock. This is why people never talk about the gameplay of 3h anymore, you spend most of the time in that game with the characters or doing decision making in the monastery.
Avoiding the school stuff actually makes your characters quite weak, especially byleth, so i recommend against it.
