Tangential but (IMO) relevant suggestion: if you haven’t already, learn to use tabs 2–6 of color calibration, as described in these excellent tutorials (follow the link to the channel and you will find them in the contents):
It is an extremely powerful module and is often the answer to a color manipulation question, and complements filmic rgb very nicely.
Regarding filmic rgb: it really improved with color science v7. If you like how it looks, why not use it?
(Personally, I hate filmic, but that’s just memories from the various “color science” iterations before, say, v6, not anything objective.)
