I would recommend to only focus on the object-level problem you’re trying to solve.
For example:
for programming, things like more monitors, a better IDE (or extensions, knowing how to navigate it by traveling back and forward, having a section with last opened files, last refactored functions, etc...) will help.
for conversations, you can apply some heuristics at different points of the conversation: what are talking about again? what did they mention? are we at the midpoint, ending, etc…
In mathematics, notation is basically a solution to the small working memory that we have, you just have to find the analogue for whatever you’re trying to solve. I doubt something will permanently fix low working memory in the long-term (e.g. dual n back) you can of course try some acetylcholine release agents or reuptake inhibitors which will make you more vigilant (e.g. the mildest one being coffee.) There’s also some evidence pointing to fasting, sleep deprivation, niche nutritional protocols such as carnivore diets (or rather, strict exclusion diets where you remove some foods progressively until you find the one that does not suit you.)

Can confirm about the use of notation. Then it becomes learning/interpreting it (including in different contexts).
Something not directly about working memory, but which I found unusually helpful in the realm of “low-level yet very general learning strats”, is the advice here: https://terrytao.wordpress.com/advice-on-writing-papers/on-compilation-errors-in-mathematical-reading-and-how-to-resolve-them/
