I am a big fan of Divvy (https://mizage.com/divvy/)—while both dated and paid, it has a wonderful feature of a visual tile map you can use. In all other cases I know, there are a bunch of shortcuts to make a window upper-top or something. But in many cases, it is not enough, as I need fine-grain control.
Divvy thankfully still works without issue and I love it, but when Apple drops Intel support via Rosetta it's going to be a sad day.
https://thelasso.app gets close, and adds more features (or visual clutter, imo), but still doesn't feel as quick and efficient to use when setting positions for multiple windows quickly. Divvy can be configured to stay open, and because it's always centered on each monitor, for some reason I can find it better than Lasso that opens where the mouse currently is.
