Hello folks.
Thank you for your replies and help. I bought a new scale that I tested, confirming all was working. I dismantled the scale and wired it up to the circuit to find...everything worked as expected!
I've also changed to using the HX711 library from gandalf15 https://github.com/gandalf15/HX711/tree/master directly instead of the endail library. I should have tried this with my original strain gauges to confirm they were an issue but I'm pleased it's working correctly now with the new gauges. At some point I will wire the original gauges and confirm if they are an issue or not.
Here is the scale with no weight added and with a 449g weight added. You can see the large spikes to 449 but also some aberrant spikes throughout - not really an issue for my purposes but still interesting interference.
Here you can see a closer version of the fluctuation in the scale where I have set the 449g spikes to be capped at 5g. This fluctation is inconsequential for my purposes and more inline with the tolerance of the gauges and HX711.
Thanks everyone for your help and I'll leave this here for anyone in the future that is struggling!
