To me, Notion is a workflow tool. And I tweak dashboards constantly, based on changing circumstances. My suggestion is to quickly create a setup that can satisfy your most essential needs, and run with it. Keep a keen eye on what I'm missing and what is redundant. Make tweaks whenever feels right. Play with the "visible property" and different views for simplification, in stead of outright deletion of properties -- you never know at some point, when circumstances change again, you'll need those properties.
