Although @setup/node as a built-in cache option, it lacks an opportunity regarding cache persistence. Depending on usage, the action below might give you faster installs and potentially reduce carbon emissions (♻️🌳❤️).
pnpm v7 or v8 (not using pnpm ? see the corresponding yarn action gist)
Based on the nextjs-monorepo-example with pnpm.
A cold cache install on the ci is around ±1m20s.
With warmed cache: ±40s + (add ±10s for compression). Crafted from benchmarks results in https://gist.github.com/belgattitude/0ecd26155b47e7be1be6163ecfbb0f0b. Depending on repo (renovatebot...), the slight complexity increase in ci setup might worth it.

Install

When a PR is closed or merged the best is to remove install cache rather than letting github reach the max (10GB) and prune.
Here's an example (feel free to adapt if you need to preserse some things, ie gh actions-cache list -R $REPO -B $BRANCH | cut -f 1 | grep pnpm will only clear pnpm related caches)

Worked great, thank you so much! ❤️
