I just re-watched
@Cooper Carter 's video, and what he does is very much in line with what I like to do.
A few differences:
I really like using an IR of my own acoustic guitar. You can buy or download IRs for acoustic, but to me it's a lottery to find a good one. I have had better success making my own, although that can also be a lengthy process, before you are happy with the result.
I run my IR in the cab block, where I also use the pre-amp features - hence I have no amp block in my acoustic preset, but I do the same in the cab block as Cooper does in his amp block.
I also apply healthy amounts of EQ to the acoustic signal.
Reverb and a sense of space is crucial, if we want to re-create our own experience sitting with an acoustic guitar. Out of Cooper's examples, I liked the Enhancer best. In my own presets, I like the "Warm Stereo Chorus", and yes the effect needs to be dialed back quite a bit. I like Rich Hall too. If you are in a dense mix, and all you are really adding with the acoustic guitar is a driving rhythm, you may need to remove all that reverb and space, so it is just dry and mono.
I use my multi-band a bit differently than Cooper - I am more aiming for re-creating the body resonance of the guitar (which not all piezo systems are good at picking up), so I am targeting a band of ~150-400 Hz that is being compressed quite a bit, when I hit the guitar hard, but then as the volume reduces, this frequency is being brought back in with a vengeance
I would probably also always have an optical compressor in my acoustic presets.
Finally, if I feel like the tone is a bit spiky, I would try a Drive block with the tape distortion selected. That is quite effective at removing these nasty little peaks.
We recently got this new 'frequency dependent' drive - I've forgotten the block name - that I really want to try in my acoustic presets, but I never got around to it.
