Thats a great way to put it, "high-write, low-read". I take a lot of notes and screenshots on calls, I may never need to go back and look but when I do look its always there. I use Onenote and the search is excellent in conjunction to the structure and tags I have build up around it. What works great is I have setup autohotkey to take a screenshot in the same area as the previous screenshot and insert it on my onenote page in context by hitting the F12 key. For me being visual with my notes is better than writing them.
Ctrl+win+s screenshots to clipboard in Win10. Ctrl+shift+z screenshots to OneNote (though an update overwrote it at one point, not sure if it's fixed in general).
You can use OneNote settings to determine how that capture is used, eg placing in the current page (I have it set to make a new page, but I almost exclusively capture to clipboard).
