I don't care about grain. Grain is IMO just noise.
And while I understand that old material just has to have grain I don't understand why there is grain in newer material.
If grain can be reduced without having other negative effects on a movie, that would also be fine.
I don't analyze still pics, I don't see a point there. I'm not watching still pics.
would the above be a good compromise, sufficient, or is there more to fine tune?

It's very difficult to compare without 2-pass, but I'd also ditch qcomp 0.7 . Between that and the Aq strength changes, bitrate at CRF 22 is going to drop quite a lot, so I'd maybe look at using a lower CRF. Maybe start around CRF 20.5 and see how you get on?
Perhaps keep AQ strength at the default of 1.0 for the time being. You really need 2-pass and short scene tests to find the optimal value.
