Take a look at Nikon D7200... it's heavily discounted right now... can be bought for under $700. That's about $100 more than a D5600, but it's a whole lot more camera for your money. In comparison, D7500 is selling for $1150, and in some ways the D7200 is as good or better.
D7200 and D5600 are both 24MP cameras. D7500 is 21MP.
D5600 doesn't have the in-body focusing motor, so is only able to autofocus AF-S and AF-P lenses. There are a number of AF Nikkors that will be manual focus only on the D5600. Some of them are still in production (such as the Micro Nikkor 200mm f/4 and Tokina 100mm Macro lens). Both the D7200 and D7500 have the in-body focus motor, so are able to autofocus those lenses, as well as the AF-S and AF-P which have the focusing motor built into the lens itself.
D7200 has dual SD memory card slots, the other two cameras have single SD card slots.
D7200 has a 1.2 million pixel LCD screen, compared to a 922,000 pixel screen on the D7500 and 1 million pixel in the D5600. The D7200's LCD monitor
is not a Touchscreen and isn't articulated... while both the other cameras have those types of LCD screens.
D7200's top continuous shooting rate is 6 frames per second, not as fast as the D7500's 8 fps, but faster than the D5600's 5 fps.
The D7500 and D7200 have almost the same autofocus system... 51-points with 15 higher performance "cross type" points, able to focus as low as -3EV (approx. moonlight) and "f/8 capable" which allows more lens/teleconverter combinations. The D5600 uses a lower specification AF system: 39-points, 9 cross type, able to focus down to -1EV and f/5.6 limited.
The D7500 and D7200 both use a true pentaprism which makes their 100% viewfinders bigger and brighter the the D5600's 95% viewfinder, which uses a penta-mirror to reduce cost and weight.
D7500 and D7200 have a higher specification shutter with 1/8000 top speed and 1/250 flash sync, rated for 150,000 actuations. The D5600's shutter is rated for 100K clicks, has a top speed of 1/4000 and a 1/200 flash sync.
D7500 and D7200 have more sealing for weather resistance, than the D5600 does.
The D7500 and D7200 both use a somewhat larger battery that gives them a few more shots per charge. Nikon offers an MB-D15 battery grip for D7200, which doubles the battery capacity as well as providing a vertical grip with secondary controls (shutter release, aperture and shutter speed control dials). Nikon DOES NOT offer a grip for either the D7500 or the D5600. There are third party (Vello) grips for all three cameras, which are considerably less expensive than Nikon grips. The Vello grip for D7200 has the same controls and functionality as the OEM Nikon grip. The Vello grips for the other two cameras only have a shutter release button (no shutter speed or aperture control dials). However, the Vello grips for both the D5600 and D7500 rely upon an external cable to connect the shutter release. AND the Vello grip for the D7500 only holds a single battery, doesn't increase battery capacity at all.
I'd recommend the D7200 anyway... but especially now since it's being offered at such a great price! Spend $100 more than the D5600 and get a WHOLE LOT more camera for your money.... But save $450 compared to the price of the D7500. Put that money toward better lenses (which make a bigger difference in your images anyway, than the camera they're used upon).
