Window Managers for the un-initiated

As I'm about to start renewing and expanding the computer fleet in my house I decided I want to have a machine solely for my personal use, where I can use some solutions no one else will feel comfortable with in the house.

I've been wanting to try window managers for a while but after researching on it for a bit I'm none the wiser on which to choose.

There are a few distros out there that already deliver this kind of experience but I want to use the opportunity to learn and start from a stock Debian and build from there to where I want to get to.

I'm fully capable of setting up my computers as is but I'm aware WMs require a bit more involvement, so having at least good documentation is a must.

I'm also not averse to learn some coding, even more when considering I want to have a fully costumized conky, but I've never coded before.

The machine will be used essentially for writing, web surfing and email and, if possible, running Stardew Valley.

Any advice will be welcome.

Thanks in advance.
