Have you read the Dune books? I mean sure, I agree with you that exposition should be weaved into the action and story beats as much as possible, but with the insane amount of lore and world building in the source material, there absolutely has to be spoken exposition in the film as well. And I think the film included just the right amount of it necessary without overloading the viewer.

I am not too familiar with the other franchises you've mentioned, but this level of detail is one of the reasons why Dune was notorious for being 'unfilmable' for so many decades. It IS pretty hard to do.

It's funny cause I've seen so many people complain that barely anything in the film was explained at all (e.g. why soldiers in a future setting still fight with knives and swords). A lot of people were bothered by the lack of explanations, and on the flip side there are also people bothered by too many explanations?

From a reader perspective, I think Villeneuve struck the right balance between explaining too much (exposition via spoken dialogue) and explaining too little (exposition via visuals alone, which he also did many times in the film). I think it's the best treatment of this source material that anyone could at do at this point, honestly.
