I think it's doable with a parametric design in Fusion but it is definitely more work up-front or re-work after you have a working version. Getting a well parameterized and set of constrained sketches can be a time consuming process since I don't do it every day. It's probably the part I've struggled with the most in making 3D printable designs (I'm not OP but design cosplay props for my kids) since I don't always know what I want the final dimensions to be.

And a parametric design requires you to buy the commercial Fusion license.

No it doesn't, unless you mean some more advanced parametric features that just the basic parameter driven modelling.
