These forum discussions seem unconnected to reality IMO. Sometimes funny, more often strange, like audiophile discussions about oxygen free copper cables. Why?
The Fuji X-T4 and X-S20 here produce images of 6240x4160 pixels, but I almost never look at images in 1:1. My 4K monitors, mostly set to 2K, display 2560 x 1440 pixels. And even when switch them to their full 4K resolution I don't view my images in 1:1 obviously. And the tablet l'm typing this comment on offers "meager" 1800 × 2880 pixels. Most family members look at images on their "smart" devices nowadays, where 2K or 4K aren't present. So even decompressed images are fine for them.
I have my cameras configured to take both JPEG (fine) + RAW (lossless) of course. Fuji JPEGs (and Canon ... etc too) are fine for most casual viewers. And if I want to crop certain parts, or adjust certain details (esp exposure), I have my RAW images as a fallback.
Storage? My SD cards are 256GB and my disks are definitely not a problem either.
I almost never look at full images in 1:1, either, but I find very often that I have the wrong lens for an application and/or the wrong exposure.
You don't have to go very far before you've cropped a 20 MP source image into a 4K or 2K image, and if that part of the image that you've wanted to highlight is not well-lit, well, exposure is logarithmic and I want all of that RAW color depth that the camera can find if I'm going to turn black or white into perceptually accurate colors.
It's true that when my framing and exposure are great out of the box, I probably wouldn't notice or care if JPEG compression cut my file size by a factor of 4...but that's not always the case.

macOS, but my understanding of Retina is that even if your effective resolution is lower (e.g., my 6K ProDisplay has a resolution of 3008x1692), applications can designate regions to be "original resolution," so I'm getting the image's original resolution in the editing window or region.
The main reason my wife shoots lossless is touch-up editing in light room. You can rescue some pretty crappy photos when all the sensor data is present.
