I'm just stating out on this, so I haven't gotten through everything I want to read yet.
Right now I'm reading Financial Intelligence by Karen Berman and and Joe Knight. There's different versions, but I choose the one "for managers". So far it's done a good job making the material understandable for someone who doesn't have a degree in finance. This the one that's more relevant to the post and will help you start understanding how companies operate at a financial level.
For personal finance I have read
I Will Teach You To Be Rich by Ramit Sethi and A Random Walk Down Wallstreet by Burton G. Malkiel. The first sounds "click-batey" but that's because "I will teach you the boring effective way to manage you're finances" doesn't sell. The latter gets more into the weeds on investing. Bother are great (though Random Walk has been edited many times and the beginning of the book has become bloated, so I'd recommend skimming it a bit since it's just history on epic financial crashes).
