Needing to use command line for some things that should be a right click, not supporting right click, ambiguities galore when looking at a package repository, odd defaults in packages that one really wouldn’t expect to have to check (e.g. Selecting RDP connection in a Remote app, but it defaults the security to something other than RDP?)

Sounds like you’re using a GNOME Desktop. You should give KDE Plasma a try instead. KDE Plasma basically gives you a Windows-esq experience without trying to install something like GNOME extensions.

For a regular user there’s not much point into going into the command-line anymore.

there’s problems like Libre Office devs …

Sure but there’s also alternatives. LibreOffice doesn’t try to emulate Microsoft Office and they never really have. They won’t even try to be compatible with MS Office but rather they do with OOXML which Microsoft created for other Office suites to be compatible with it but then just never supported it very well. Some alternatives do however. WPS Office is perhaps the most popular alternative for this that does try to be compatible with MS Office and emulate its feel and features but ONLYOFFICE is also a contender.
