Since you asked, I assume you are a beginner at this.
1. Pay attention to color balance. I suggest not relying on auto color balance, because it is inconsistent, and often not even correct. I suggest setting color balance as well as you can when you make the exposure.
Editing raw files allows for changing the color balance after the photo is taken. And it's a lot easier for me to get the correct colors and contrast with raw edits -- it just way more flexible than editing jpgs.
I've used "gray" or "white" areas on the photo to adjust the color balance in the editor, using the pinpoint selection tool. There often aren't good areas to pick, though.
I usually change the white balance a little, to get the effect I want. Forest in shade, for example, is very blue-green with the light filtering through the trees. I want it warmer, closer to olive green, to match what my eye sees.
2. Learn color calibration and profiling of your monitor and printer-paper combination. Other than that, don't mess with it. That much is hard enough.
Do you use a calibration device? How else can you calibrate the monitor?
This one is less expensive than some of the devices, but it's still $120. C

I got a similar device some years ago, and it's effective. I did see that my 4K monitor only needed minor adjustments from it's factory settings. I suppose some monitors can need more significant adjustments.
2. Beware of global color adjustments. It's too hard to get it right and too easy to get it wrong. Usually the camera can do it better than you can. If you have to make major adjustments, it could be difficult to get it right.
I'm not sure what this is referring to. Do you have an example?
