Writing compilers is a pretty specialised undertaking, so general guides are rather hard to come by. For FPC, your best bet is to study the source code of something that already exists, make notes and build from there.

Hello. Are there any guides for those who want to try adding something to the compiler?

No, there aren't.

For example, I would like to try making a new backend. Is there some example template, etc? Or just other backend code examples?

Best is to use an existing backend and ask questions here.

The AArch64 backend should be fairly clean as a starting point.

Sorry, I didn't mean to imply you were a
novice, just a slight warning to be prepared
when you dive into the code!

Some documentation would be nice for the
compiler, but I'm not sure where to begin
there except maybe with outlining the
individual compiler stages (creating nodes,
simplifying nodes, building target-specific
assembly language, peephole optimisation
etc.)

There are a couple of wiki pages with some information, see e.g. https://wiki.lazarus.freepascal.org/Porting_Free_Pascal and the links at the bottom of the page. It is unfortunately not very detailed and outdated, hence the advice to rather look at existing backend code.
