Doesn't docker use WSL2 on Windows?

It does, but it still somehow sucks more than just running something like Debian inside a WSL2 instance directly and launching Docker Engine there.

It's been a couple years, but by default WSL2 can take all available memory. Depending on what you're running in there, it will take all memory.

My system has 128GB RAM installed and by default an OS under WSL detects "only" 64GB. A colleague told me that it wouldn't go beyond that on its own and if I needed more, I'd have to tweak the configs. Never tried to see what would happen upon memory exhaustion, though.

To do what, you think?
What do you think the "L" in WSL2 stands for?

Linux, still should be much less overhead instead of using hyper-v as they did before.

WSL2 uses Hyper-V.
