For most everyone, pixel resolution at 20MP is more than enough for any editing and / or printing needs. That 20MP to 20MP range is what the 'working professionals' need for a 2-page spread (magazine print), as if anyone was still printing or purchasing physical magazines in 2024. We see this reality in the slow upward migration of the top (flagship) pro DSLR models.
Examples:
Nikon
D3X - 24MP, 2010
D5 - 20MP, 2017
D6 - 21MP, 2020
Canon
1Ds-III - 21MP, 2007
1DX - 18MP, 2011
1DX-III - 20MP, 2016
Meanwhile, at the same time those flagship models were being released, all around the $6000 per body price range, even the entry-level models were reaching a standard 24MP resolution. The 'pro' full-frame models at one level-down from the 'flagship' bodies reached a 30- to 50MP range for the same timeframe, examples like the D810, D850 and 5DIV models, as well as the top full-frame mirrorless bodies typically all coming out around 45MP.
Personally, for my wildlife photography, I can 'see' the difference in cropping into the results in FF cameras with the same focal length lenses, where one body is 22MP and the other 24MP. I have more options with the images (camera) that has more pixels, even just a 2MP difference. I've also seen demonstrations of the massive print sizes and massive fine details of architecture and cityscapes captured at 45MP.
But again, for most everyone not shooting distant wildlife and not printing anything, buying bodies (sensors) beyond 24MP is just wasting money on capabilities you'll never need.

Regarding cropping: The key is not the number of pixels; it is pixels on the subject. This means you need to access the camera lens system, not just the camera.
