https://wiki.freepascal.org/Codetools
And then look at the examples in lazarus/components/codetools/examples.

It's basically the same as opening a new tab/window but it's more for really quick references. I'm not sure how it's implemented in LSP but maybe you could return the line number and file name and the client does the rest.

FindDeclaration gives you the line and column. You can also get the source span of the declaration.
And there is FindSmartHint, which returns a brief text for a declaration including some context like type/var/const, private/public, parent class, etc.
