The first thing to do in Lightroom is to scroll down to the Camera Calibration area and change the profile from "Adobe Standard" to "Embedded", which uses the camera's own embedded colour profile instead of Adobe's rather flat-looking default. I also apply lens corrections if the profile for the lens exists. I have the camera and lens profile changes set up to apply at import for each of my cameras.
Then, using a preset I've set up, I typically apply Contrast +10, Clarity +10 and Vibrance +7, and a very, very gentle "S"-shape to the Tone Curve - Highlights +3, Lights +5, Darks -5, Shadows -3, or something something like that.
Finally, I'll tweak the Exposure, White and Black point, and Highlights and Shadows to suit. This is done manually.
That should get you started for the post-processing, at least. It'll give a little bit of richness and pop to your photos as a starting point, and you can take it from there
