A 4K monitor full screen is about 8 megapixels. Anything with more resolution is wasted online unless your lens requires to crop because it doesn't focus close enough.
I'm using a 12mp full frame Sony A7S that is 15 years old.
If your phone does macro, you can get some decent phone shots.
These are with OnePlus 12 phone.

When I break out the Sony is when I want to use the lens to add pleasing distortion. Similar to how certain orders of distortion make a guitar sound 'better'

Or when I want to show more detail that cell can.

Either way if you want to take a good close up the camera has to be rigid or you'll get blur because of the long shutter needed. I use a small tripod and a phone clamp. You must shut the fans to keep them from swaying the plant.
I also knock my exposure down 1-2 stops on the phone because the grow light causes overexposure. Alternately you can shut it and use flash or other fixed lighting. I've used a strong flashlight effectively at times.
