Thanks so much Chris, this is really great info. The way I’ve been working is with the 2nd option you describe, as is also outlined in the https://generalspecialist.com/ link.
The only difference is I haven’t been setting and input LUT on RBG sources to convert from Video to LogC, but instead have been turning down contrast and saturation as necessary so the composite works under the top layer adjustment layer. Is this destructive to my RBG footage? Isn’t an input LUT on the layer from Video2LogC effectively doing the same color work on the RBG footage, just as a quicker way to get there?
Blending modes behave differently with the input LUT on. Screen no loner makes black transparent (because black is more grey from the LUT). Though the “lighten” mode seems to work like screen using this method. Is that normal?

nothing is destructive if its a guide layer. you don’t have to use luts for things, they are simply luma and chroma changes you can do by hand. you can make your own technical luts that work even better than manufacturer’s luts with better detail and skin tone line. luts aren’t smart, they don’t know what exposure and iso you use. they only care about white balance. and yes, linear light affect blending modes differently. fxguide has many good reads on that.
