My views on these issues may not help anyone but me. I just trust my hearing and determine what I like. I experiment somewhat with all the settings, doing comparisons among the changes made. I don’t use any set formulas. I compress lightly, but not to the point of pumping and artificial sounds coming through the speakers. On EQ, I go for clarity, especially on the vocals. I cut the bass somewhat and gently boost either the mids or highs. Don’t like boominess. I check vocals against the style playback to see that they cut through the mix. Also, don’t saturate everything with too much reverb. Reverb in excess sounds artificial and is a distractor. You might have others give a listen and get their feedback, as well.
