So, and I understand this is a rookie question, would you say a lot of people would prefer a full frame 24 mp sensor over a crop sensor 40 mp? I figure that’s a matter of opinion to an extent as well
That's dependent on what area your lenses cover. If the system contains mostly lenses with full-frame coverage, they're kind of wasted on a DX sensor (half the image area projected by the lens is simply dismissed and not recorded). 24 MP FX gives excellent low-light image quality and very good general purpose image quality. A higher resolution sensor is mainly needed when one intends to crop the images depending on the image (i.e. cannot predict and use a longer lens because one doesn't know exactly what one will need for the shot). 45 MP FX is also a good general purpose sensor but clearly more targeted towards high-end applications where the best image quality is desired and there is either plenty of natural light or adequate lighting is provided using artificial light. With the 24MP FX sensor you can record quite good image quality in next to no light (the 20 MP FX is still better in this niche but not available yet for Z cameras). This is nicely combined with the Zf's high sensitivity of AF in low light, advanced VR, and the way the screen can be folded towards the camera's back so almost no light is emitted from the camera (which could be distracting to people in an environment where there is very little light).
40 MP APS-C can be a good choice if you have the APS-C optimized lenses for it, and there is no reason to avoid it if the Fuji system meets your needs. I'm personally unconvinced by Fuji's autofocus especially for approaching subjects and high fps, when I've tested their cameras in this way the results have not been good. A Zf can handle most subjects approaching the camera and the Z8/Z9 are still better (more precise), and I have high confidence in these cameras in the situation where a human subject approaches the camera. With animals it's a different story and Nikon has some more work cut out for them in this area. However, if the Fuji meets your needs regarding AF then obviously money can be saved by choosing the smaller format. I have existing lenses that cover 35mm full frame and I like photographing people including indoors in very low-light environments (of course I prefer good light but sometimes it's better to get some images rather than none when the light is poor) and the Zf is great for that application, and I've grown very fond of the camera because of handling and the results.
I think choice of a camera should above all consider the overall system, which lenses are available, and what lenses you actually need or want, and is the total cost acceptable.
