I use multiple materials from multiple brands, so yes, I do some calibration for each filaments.
I usually limit myself to the flow factor by printing a cube in vase mode and then adjust by ±2% after a print if I feel like it is needed.
For the temperatures, I go for the normal recommended values (200°C hot end and 60°C bed for PLA) without any calibration, unless there is a problem. (I think last time I printed one was for ABS because it kept curling up…)
Retraction and Linear advance seems to always give roughly the same value for each type of materials, so I ended up using an average which work well enough.
I printed a case for a small PC that I user as a home server 3 years ago, and I used the cheapest PLA out there. No warping, nothing broke. It is cooled by a single 80mm.
As long as there’s enough airflow to prevent the PLA from actually heating up, it will be fine.
