There are plenty of test objects available, like Benchy to the Nth degree, but I’ve seen very few setups for tuning other than trial and error. There are temperature towers, and the linear advance stuff is typically tuned by sweeping the parameter space, but these are the exception.
Someone needs to make a tuning regimen that sweeps all the major parameters to pick optimal values, which in general could be different for different filaments. I started on a test pattern generator for this but it requires a substantial amount of work.
