Node based pipeline automation and workflows

Am currently looking into a decent toolset basically lkike this (asked on Slack) and got pointed here.

This was my ask:

Does anyone have any recommendations on a neat little free (preferably Python and preferably open-source) library that can make a flow of tasks/steps to perform with configurable options for an artist to be configured. So, something like a simple node graph of ordered list of tasks to perform where its trivial to implement the “steps” that are available (e.g. simple classes, or simple entry points) but something that when given to an artist they quickly have an idea on how the tool itself works.
The artists are familiar with node graphs (like Fusion, Houdini, Nuke, Maya).
Basically I want to build a few simple steps they can put after each other as a ‘sequence of actions’ to perform in e.g. a certain workfile and then let them batch run that on say 100s of workfiles. And I just want to provide them some simple tasks with configurable options they can put in that sequence to run.
I feel like I don’t need a crazy Houdini PDG or Gaffer tool at this stage since there’s lots of overhead to learn the tooling itself.
Any recommendations are welcome! Feel free to also steer me into a completely different direction. Just curious to hear thoughts on how others might deploy (or dream to deploy) something like to artists.
The idea is that the stacks they build would get submitted to the farm per e.g. file to run it on so that one could easily queue: do these hundred steps on these hundred shots with this “context”
Even just typing this here makes me think that no matter what I end up what this will end up being way bigger than just a few tasks to expose to an artist. :') Anxious to hear everyone’s inputs/links/references/ideas!

Given that, I wonder if anyone in this topic ended up looking into any of these mentioned options or would nowadays recommend another?

I also had flowpipe on my list which got mentioned in a Rise VFX studio presentation but I’m not sure if there’s a visual toolset around that.
