Drupal 9 (our current install) uses CKEditor 4, when we move to Drupal 10, it uses CKEditor 5. CKEditor 5 is currently installed in core/modules, but not used.
We currently have 2 or more versions of CKEditor we use plus extension of the plugin in 2 other components.

CKEditor versions are in:
core/modules
or the version in:
modules/contrib
But the one thing to consider is that we are still on Drupal 9 right now, when we move to Drupal 10, we will need to switch from CKEditor 4 to 5, because Drupal 10 only works with CKEditor 5 which is currently installed in core/modules, but I think it is not currently used.
So far it looks like the only version been used is the one in:
modules/contrib
We will have to decide which ckeditor to use. But a lot of test needs to be to avoid breaking another module/component that may of the off chance be using the one we will delete.
Drupal 9
Our current Drupal version D9 uses the CKEditor 4 in modules/contributor folder.
Drupal 10
Once we upgrade to Drupal 10, will need to move from CKEditor 4 to 5. That is because Drupal 10 does not use CKEditor 4.
Samples of CKEditor 5 we can explore to integrate/use can be found here:
