If we are going to change this, I think you should just change it to C++20.

We aren't trying to retain C++11 compatibility?

You could also update the CMake minimum required to `3.22` (just matching the Core minimum required).

We don't use the CMakeFiles from this repo; we just compile the objects we want directly, using our own options.

> This change only partially resolves https://github.com/bitcoin/bitcoin/issues/32391 What is left unsolved after this PR?

> But, it probably would still make sense to close https://github.com/bitcoin/bitcoin/issues/32391. Yea, on our side, this should be enough to close #32391.
