What are some useful ratios for investing to look for other than PE, PS, PB etc.?

Ratios are a very important component and whenever I google about it all i see is people trying to list the same commonly used ratios (everyone knows about these ratios), and i honestly don't feel these articles/videos are adding any value to us.

People should be discussing more advance and deeper ratios (prolly like PEG or ROIC or something). Can you list down some interesting ratios that you use while investing or judging a company before going in deep?

This discussion woudl be more value adding than anythign else.
