This is where IMHO QGIS official documentation should have a say and play an authoritative role, with up to date, clear and meaningful instructions. This topic of configuring QGIS with python environment is to some extent "discussed" at [0] and [1]. Do these pages meet the conditions to play that authoritative role? I'm not that sure, given how recurring the topic arises, but TBH I'm not versed enough in Python to be fully credible.
