I mean tbh most of the new gen is boring and faces hardly any struggles. The only one shown to actually have suffered is Sumire IMO. None of them have had to face any real danger, death, war, slaughter, true loneliness.. etc. So all of them are basically copies of Naruto's gen without any brutal ninja world reality, add or take a few personality traits and abilities. Therefore, nearly all of them are "boring" with the logic you're using.
In reality, many of the face lesser struggles, but more realistic and average ones. The insane brutal ninja struggles will come in due time (look at the time skip alone). Personal battles will be fought by team 7 I'm sure. It's just the route they decided to start the story on in combination with the horrible pacing that makes this seem lack luster. (I mean it is, but it seems like things are picking up finally).
Sarada has to struggle with not seeing her father much at all and a lack of her mother for most of the weekdays (I assume). A struggle on a personal level that will (and has) lead to character development.
Mitsuki is still figuring out his direction and who he actually wants to be. Also a struggle at a personal level that leads to character development.
Boruto so far doesn't have to struggle with the seal and Jougan as of late, so it can be said his struggle is a father too busy and tired to really talk to him. A personal struggle that once again; leads to development.
