How to quickly recolor icons in Illustrator?

Question

Adobe Illustrator

Greetings.
There are many icons in the file. All one color. I wanted to make it so that I could select everything and click on change the color of the stroke and fill, but there are shapes with a fill, without a fill, with and without an outline. If I select all the icons and, for example, choose a fill color, then the fill will appear for those shapes that have it turned off. The same applies to contours - I choose the color of the contour and the contour appears where it should not be. Is there a quick way to change colors, or in this case just select individual elements and change their color?
For example, we can take two shapes:
- a square with a fill and without an outline
- a square without a fill and with an outline
