Color depth refers to the number of unique colors that a sensor can faithfully capture. Cameras with better color depth will demonstrate smoother transitions from one color to the next, and avoid "banding" in areas with subtle shading. (Blue skies are an example of where you might see color banding.)
More color depth is generally better, but you'll struggle to notice a difference between two cameras with less than 1 bit of difference. Color depth above 22 bits is considered excellent.

Cameras with higher effective ISO will be better choices for indoor photography, night shooting, and indoor sports photography, especially if you intend to make large prints.

5D Mark IV test data on DxO Mark D300S test data on DxO MarkCameras with more dynamic range allow you to take photos with dramatic differences in highlight and shadow areas while retaining detail in both.
Think of a brilliant sunset on a rocky beach: Bright sunset in the background, with dark rocks in the foreground. High dynamic range means more of the extremes will be faithfully reproduced.

5D Mark IV test data on DxO Mark D300S test data on DxO MarkRugged construction; 51-point AF system capable of sophisticated AF tracking; Large, bright optical viewfinder; 7 fps JPEG or 12-bit RAW burst mode; HD Video capture.
14-bit RAW mode slows continuous shooting from 7 fps to 2.7 fps; Somewhat slow AF for a camera at this level, especially in 51-point auto-area mode; Video capture tops out at 720p24.
Superb image quality from RAW files; Improved dynamic range; Excellent high ISO performance; Fast 7fps burst rate with unlimited JPEG buffer; High-quality cinema 4K video; Built-in Wi-Fi; Dual Pixel CMOS AF is very good.
JPEG files look soft at default settings; 1/200s flash sync; 4K video codec is cumbersome; 29:59 continuous video recording limit.
