I have one or two reports that fit pretty well into a group like you, who talk about "all of those things" outside of 1:1s. Totally a valid position! We still do a 1:1, but those turn into sort of work-tangential conversations, things like new tech that we're experimenting with on the side, or ideas for features that might be fun, or ways that we can incorporate the things they want to do into future roadmaps. Maybe it's not the most productive thing, but it can be fun, and sometimes you can be surprised by what comes out of a really good 1:1.
As sort of an example, I had a guy on my team that was super smart, highly productive, and he didn't need much hand-holding. We'd schedule 1:1s, and they would go well, but we'd also talk almost every day about the kinds of things that would normally come up in 1:1s. Just like you're describing.
We shared direct feedback regularly (he got distracted easily), we talked about the way he interacted with team members (which wasn't always great), the projects that he worked on (which were not necessarily the ones he wanted to work on). It was, on the surface, a good relationship, but obviously not a great one.
Then one day he mentioned off-hand something about his immigration status. My ears perked up, and I said "Tell me more." So in our 1:1, for probably 2-3 sessions, we talked about nothing but immigration and how it works, what his concerns were, and how much energy he spent thinking about his immigration status. Then he taught me about how the H1-B priority levels worked, and in the midst of that conversation, something clicked.
The reason this guy was easily distracted and the reason he was unhappy with the projects that he was working on wasn't because he had ADHD or thought the work sucked. The reason was because the projects he was working on were not things he could show to Immigration and say "See, I deserve a higher priority."
Once I had that realization, I was able to zoom out a bit and find projects that would give him a leg up on the prioritization scheduling. I was able to find time to let him work on white papers and formal, published research. He was able to patent something that we worked on. I helped him find conferences to give speeches at. All of these things he tackled with gusto and enthusiasm and, incidentally, fit into our company's roadmap.
Without that 1:1 that was seemingly unnecessary, I never would've made this connection, and he would still be miserable. Now he has his green card, just 18 months after that conversation, in part because he was able to demonstrate that he met certain criteria to the immigration authorities.
I understand the perspective of "I checked all the boxes outside of the meeting, why do I need this meeting?" but I encourage you to consider some of the softer values of the meeting. Even things as simple as getting to know your manager and finding out you have things in common will help.
It kind of sucks, but the more people can view you as a PERSON and not as a RESOURCE, the happier you both will be. And part of that involves spending lots of time with someone offline.
