By default the linking should work like this.
[[Page Name]] will create a link that looks like Page Name. I'm guessing though you have duplicate notes with the same name. When that occurs it can't use just the name so it defaults to showing the path to the duplicate note again. Usually this is rare as it's not often people will have 2x notes named the same thing.
As you have discovered you can rename a link with a pipe so [[page name|new name]].
You can also preview a note from within a note by adding an ! mark so ![[page name]].
You can also setup an Alias for a note in the front matter. At the top of your note you can do this.
---
alias: "Second Name"
