One of the tools I need to be able to use is esptools - -  well in the

then I need to have python3.12 and that's also not part of Devuan4.

In this case, if Python-skill is a "personnel-resource" (and C++ a

 Well - - - RPi world technical specs is usable from -20 to 60 C (iirc on
the top number)
and for my project I absolutely need to have usability to at least -40 - -
could possibly do a bit less but -35 C is a hard requirement so the RPi
and Pico (which I would like to use) is out but ESP8266 runs in that -40 to
65 C
range.

Interesting, but creates a mis-match of tools - battles for you to fight...

Why talking of Python 3.12 when the solution involves MicroPython?

 Because one uses psytool on one computer to transfer a program to the
MicroPython system.  In fact there are a set of tools that need Python3.12
to be able to do this and therefore the question.

Perhaps need to take a step back and look at 'options' - relate needs to
resources, and evaluate the impact of each decision on later ones - as
well as against your personal skills (modify objectives to limits, or
accept that some learning/training will be necessary as pre-requisite to
(being able to) attack the project).

I have been investigating using a venv but am not finding clear directions

so
that I could set up Python3.12 inside (along with the other needed tools).
The
more I'm looking the less useful most of the information I'm finding is
becoming.
Therefore I thought I would go to the python gurus for information - - -
which I
have.
 So please - - - how do I set up a venv so that I can install and run python
3.12
(and other needed programs related to 3.12) inside?

If you mean venv itself, which "directions" have you reviewed?
This one (https://python.land/virtual-environments/virtualenv) seems very straight-forward and shows "What's inside a venv?" to include python.exe. Given that venv is more-or-less the official/traditional solution, what are you doing differently - perhaps the question is lacking detail.
(see also @Cameron's take)
Personally, I'm using Poetry (https://python-poetry.org) which seemed just as easy to pick-up; plus pyenv to maintain multiple versions of Python on one machine.
