What used to work for me is to build a single list every morning (based on yesterdays list) and then just do it one after another without allowing myself to prioritise after that point.
My largest executive function issue is the guilt of not doing some other thing.
If I have a very stressful situation, I can easily organise my thoughts and ruthlessly prioritise what is important from what is not important.
In "peace" times, this doesn't work at all, and instead if I have something that I know will take half a day (say, for example, fixing a subtle bug in the email system) then I will feel guilty about doing that over something else (say: doing paperwork for the worked hours that month).
I'm very similar to you and going through similar issues.
I've also started to write a to-do list on paper and keep it always open in front of me on my desk. This is the only thing that seems to work for me. If I keep a virtual to-do list, I lose track of it, forget to check/update it and it eventually becomes useless.
You're not alone, hope you find something that works for you!

Thus, I do neither. Until one becomes critical.
It's fucking stupid, but I can't fix it.
