Of those I feel python is the big problem, at least if one deals with multiple projects needing different versions. When you've finally got the paths and venvs correctly set up, many packages won't be installed correctly because there is no wheel for M1 / your architecture. So then you have to compile everything yourself, which then fails on some new steps.
