Unpopular opinion but Sharepoint is not sure difficult once you understand the basics of lists, document libraries, how pages are created/edit, and so on.

There's a great deal of flexibility in how a list/library is designed. You and your peers may not have permissions set correctly. Also, checking in/out documents and can be disabled.

Also with the introduction of SharePoint Framework a few years ago (ie: more or less inserting angular/react components that interact with list data), a "SahrePoint Developer" can be more or less a regular developer with a little domain experience.
