Rectangle (OSS), Moom, and Magnet are all good options if you want to go beyond what Sequoia supports. I've used Moom for years and particularly like its behavior when external monitors are added/removed.
Yes it's not free, but it's a cheap one-time purchase and I've been using the same license for a decade now, so it's close enough to free that the difference is moot.
I kinda like the ratpoison or i3 approaches to window management (which I’d characterise as “don’t worry about it, I’ll just do the right thing until you tell me to resize or rotate or whatever”) better though.
