I've been a part of a lot of CG threads over the years. It's right up there with engine tuning as topic that people get way too stressed out about and new people tend to overthink and ridiculously bad advice gets tossed around about. The designer knows what the CG should be, and any of the online calculators that take the tail specs into account will give you a good starting place if you don't have the manual. After that it's all about feel, how the plane behaves in the air. Within a range, CG is a matter of personal preference. Go fly the plane and see what you think. We can't tell you what feels right to you.
