Have been trying out
(setq show-paren-when-point-inside-paren t)
This only works when cursor is just inside the opening parens. Is this how it is supposed to work?
The name itself has tendency for confusion.
If it was me, I would not mix the highlighting of parens with highlighting of expressions. Instead have two autonomous functionalities, one for highlighting parens only, another to highlight expressions only.

Yes.

You are supposed to read the doc string, not just the name. Names
cannot be too long, because it becomes inconvenient. And the doc
string explicitly answers your question.

Could this simply be included as a style for `show-paren-style`? Showing the parens
wherever point you are in paren would also be useful.

No, because this isn't a style, it's orthogonal to the style.
Style says _how_ to highlight, whereas this variable says _when_ to
highlight.

Which means that one can have `(setq 'show-paren-style 'parenthesis)` and
`(setq 'show-paren-when-point-inside-paren t)` working concurrently.
The following are just some thoughts.
Emacs can do without variable `show-paren-when-point-inside-paren`. Because `(setq 'show-paren-style 'parenthesis)` highlights parentheses depending on the position of point. This holds also for
`(setq 'show-paren-style 'expression)` and `(setq 'show-paren-style 'mixed)` (the latter requiring matching parenthesis to be outside the window pane).
Have also noticed that with `(setq 'show-paren-style 'parenthesis)` and `(setq 'show-paren-style 'mixed)`, the style overrides the `show-paren-when-point-inside-paren` setting.
An enhancement to `(setq 'show-paren-style 'expression)` can also be made such that the sexp at the current point can be highlighted. Thus, if cursor is between two sexp's inside a structure (e.g. an `if` condition) the entire structure can be highlighted.

The highlight-parentheses package implements this:
