Go-to plug-ins are Channel EQ and Compressor, then a reverb plug-in on an Aux and send your tracks to that Aux.
Then depending on what's needed, an Exciter if a track is too muffled, a transient designer (like Logic's enveloper) if an instrument needs more attack, distortion if a track needs more character, a modulation plug-in if a track needs some motion, etc...
