Is the corneal epithelium best described as a simple epithelium, cuboidal epithelium, stratified epithelium, flat epithelium or all of them? Thanks

Do you know what the different types of epithelium are? Do you know the difference between a simple squamous epithelium and a pseudostratified columnar epithelium? If not I would suggest you look into this, I will provide a basic explanation.
Simple = one layer
Stratified = multiple layers (strata)
Squamous = flat
Cuboidal = length and width of each cell are roughly the same
Columnar = length of each cell is greater than the width.
There are also further modifiers such as whether it is keratinised, or ciliated for example.

The corneal epithelium is "compound" i.e. it has more than one type of cell..

It has overall 6-7 layers of [so stratified] and, of course non-keratinized [for transparency].epithelial cells.

There is a single basal layer [innermost] of columnar cells (see jpw's post above); then 2-3 layers of "wing" cells and lastly [on the surface] 2-3 layers of squamous cells [squamous cells appear sickle-shaped in cross-section, but a good analogy for the 3-D shape is a single corn-flake].
