The simplest way is to use front matter parameters.
Regarding .Render I quote from this post:
The other way would be to use conditional logic in your layouts/_default/ templates to output different layouts per .Page Type/Section.
However the latter can get convoluted. Also to achieve it you would need to use one template to rule everything.
Also do note that resources is a reserved name space in Hugo. See: Page resources | Hugo
I would rename the Resources post type -if I were you- to avoid possible problems down the line.
