Should I cite a paper for its literature review?
There is more controversy on this topic than I expected, so I've done some further digging. The results of this surprised me!
Institution, Program, and Journal requirements
The rules of your neighborhood may differ, so you'll want to follow whatever more specific rules are given to you in your program. For example, Columbia College demands secondary source citation:

Indebtedness
You must cite any text you read that helped you think about your paper
even if you do not reference it directly in the text of your paper.

However, the OWL APA style reference gives differing advice:

Work Discussed in a Secondary Source
NOTE: Give the secondary source in the references list; in the text,
name the original work, and give a citation for the secondary source.
For example, if Seidenberg and McClelland's work is cited in Coltheart
et al. and you did not read the original work [emphasis mine], list the Coltheart
et al. reference in the References. In the text, use the following
citation...

So if you merely were directed to the original work, but then attained the original work and read it, there is not necessarily any need to cite the secondary source - but the guide doesn't prohibit it.
However, the IEEE has a stance as strong as Columbia, but in the opposite direction! As noted by York University in their IEEE style guide (page 5 of the pdf):

Should I use secondary references?
A secondary reference is given when
you are referring to a source which you have not read yourself, but
have read about in another source, for example referring to Jones’
work that you have read about in Smith. You should avoid using
secondary references and locate the original source and reference
that.

Murdoch University has an even stronger interpretation:

• IEEE style does not allow for the use of  secondary source.
• Locate the original source of information which is cited in a work
which you have read.
• If an original source cannot be located, it should not be cited.


Jeeze, no wonder there are so many different answers!
So it would seem there cannot be a one-size fits all answer - it depends. What is required in one field and style is forbidden in another, and optional in a third (and apparently even then people differ).
