Now you know Shells, so you should first spend some time reading zsh

TAB and following options should do the job
setopt automenu autolist should help too

It's even better than just seeing what is there just type TAB again and
one after the other possible extension is used.

man zshopt

and you should check the compctl or the like for cd it might look like:
compctl -g '*(-/)' cd rmdir

which means that you want after a cd just directories as expansion.

guess zsh makes this automatically. But don't know
