As is often said here and everywhere, including this thread already, acoustic guitar recording results depend on the sum is a lot of variables.
But, many of those variables can be addressed either going in right, which is where you want to get to, obviously, or with some careful work in the DAW, assuming you get close during the tracking.
It seems to me like you're trying to guess how to get from A to B, without really understanding the difference between A and B. So, go back and start with your reference tracks, and then your own tracks. From a final result POV, e.g., if it's compression, it honestly doesn't matter much (IMO) whether you do that going in, all ITB, or a little of both. What matters is the result. Same with EQ, etc.
Short story long, there's just a lot of ways to skin the acoustic guitar recording cat. What you need to do is refine the basics, and especially work on the space and mic placement basics. Post a raw track (via Dropbox) and tell us where you're trying to get with it.
