Some projects provide nightly builds or other versions which are simply the latest code version which might not be stable but all the more public versions are supposed to be stable. You can find the latest version information here: https://github.com/ethereum/go-ethereum/releases so just take the version 1.9.13 (latest at the time of writing) and it should work just fine.
The same is true for both light and fast sync modes.
