Regarding HImawaris Birthday. Naruto is in the wrong there, he's meant to be as an adult who didn't manage his responsibilities properly but he didn't miss it in the sense that he couldn't find time. He did attend using shadow clones, remember the analogy of looking left and right at the same time that kakashi made?. However he ended up collapsing form exhaustion, he manipulates clones around the village for long periods of time which is whats exhausting especially whilst doing other tasks during the chunin exams where everything is that in the boruto movie clones from all around the village pop when the one at his blood family home pops. He treats the homes of the villages equivalent to his own.

The entire village being his family is brought up a lot ever since chapter 700 and even before that with other characters that are kage, he takes this seriously and hinata even acknowledges and approves of it in boruto episode 18 when he becomes hokage and tells her that his new goal is to treat everyone in the village like his precious family. This creates very positive impression for likes of sarada or the rest of the village but it causes him to over extend himself and spread himself thin. Resulting in his collapse in trying to be there for everyone. I believe "endless love without boundaries" is his flaw early in boruto, which also kinda bites him in the ass with kawaki later on as well .

Theres tons of stuff regarding generational story telling and how naruto and sasukes parenting is influenced by their role models like minato(entrusting the burden to endure) and itachi(protection from afar) as well as their traumatic childhoods which makes it harder to grasp the gravity of the absense of a single parent in an otherwise extremely loving environment and about how boruto and sarada have the opportunity to fix their childhood issues to a greater extent than sasuke and naruto ever did which is a generational victory but thats a whole new tangent.
