Looking at various shading languages:

MSL

enum class access { sample, read, write, read_write };
texture1d<T, access a = access::sample>
texture1d_array<T, access a = access::sample>
texture2d<T, access a = access::sample>
texture2d_array<T, access a = access::sample>
texture3d<T, access a = access::sample>
texturecube<T, access a = access::sample>
texturecube_array<T, access a = access::sample>
texture2d_ms<T, access a = access::read>
texture2d_ms_array<T, access a = access::read>  # OSX Metal 2.0, IOS ???

depth2d<T, access a = access::sample>
depth2d_array<T, access a = access::sample>
depthcube<T, access a = access::sample>
depthcube_array<T, access a = access::sample>
depth2d_ms<T, access a = access::read>
depth2d_ms_array<T, access a = access::read>  # OSX Metal 2.0, IOS ???

For texture types
(except depth texture types), T can be half, float, short, ushort, int, or uint. For depth texture types, T must be float.

HLSL

Object1 [<Type>] Name;

Object1 Type | Description
-- | --
Buffer
Texture1D
Texture1DArray
Texture2D
Texture2DArray
Texture3D
TextureCube
TextureCubeArray


Object2 [<Type, Samples>] Name;

Object2 Type | Description
-- | --
Texture2DMS
Texture2DMSArray

Type | Optional. Any scalar HLSL type or vector HLSL type, surrounded by angle brackets. The default type is float4.

I'm not sure what the depth equivalents would be in HLSL.

GLSL

gsampler1D 
gsampler2D
gsampler3D
gsamplerCube
gsampler2DRect
gsampler1DArray
gsampler2DArray
gsamplerCubeArray  # requires GL 4.0 or ARB_texture_cube_map_array
gsamplerBuffer
gsampler2DMS
gsampler2DMSArray

For `float` the `g` goes away, for `integer` the `g` becomes an `i` and for `unsigned` the `g` becomes a `u`

WGSL

Given the above I'd propose something like the following for WGSL.

texture_1d<type>
texture_1d_array<type>
texture_2d<type>
texture_2d_array<type>
texture_3d<type>
texture_cube<type>
texture_cube_array<type>
texture_2d_ms<type, size>
texture_2d_ms_array<type, size>
