These are some of the tools that have made my life in the terminal so much easier over the last years. Also, all of them work inside WSL2 without any hassle.

My other lists:

• Fantastic (and lesser known) VIM Plugins
• Great Coding Fonts

nnn

A super fast, fully-featured terminal file manager with a minimalistic interface and less/VIM-like keybindings (navigation with hjkl, search with /,...). Also offers some useful plugins like instant preview, "open with", "go to git main directory", etc. Can also be used as quick file system navigator (can change to last active dir on exit).
As an alternative to the usually pretty outdated versions in OS packages you can just donwload one of the statically linked executables on the GitHub release page.

broot

Fast file browser and manager that displays a tree that is automatically partially collapsed so it fits the terminal height. By default the primary mode of navigation is a super-fast search, but one can also switch to a VIM-like modal interface. Broot offers working with multiple panes and a staging area for operations on multiple files. The instant preview pane can also diplay images right out of the box.
Broot runs on Linux, Android, Windows 10+ and OSX. Binaries can be downloaded from here.

cargo install --locked --path .
pkgin install broot 
emerge broot
apk install broot
port install broot

exa

An improved file lister with more features and better defaults. It uses colors to distinguish file types and metadata. It knows about symlinks, extended attributes, and Git. And it's small, fast, and just one single binary.

apt install exa 
dnf install exa
emerge sys-apps/exa
nix-env -i exa
pacman -S exa
zypper install exa
brew install exa 

ncdu

A disk usage analyzer with an ncurses interface. It is designed to find space hogs on a remote server where you don't have an entire graphical setup available, but it is a useful tool even on regular desktop systems.
Packages are available for almost all operating systems.

fasd

A command-line productivity booster. Fasd offers quick access to files and directories for POSIX shells. It is inspired by tools like autojump, z and v. Fasd keeps track of files and directories you have accessed, so that you can quickly reference them in the command line.

pacman -S fasd
brew install fasd

fd

ripgrep

pacman -S ripgrep
pkg install ripgrep
