Is it better to run ChkDsk /f first, then Sfc /ScanNow or is it better to run the other way around, and does it matter which is run first, as I see no guides online saying which is the best option?

The two commands are very different and for different purposes and, from this perspective, it does not matter which one you run first:
CHKDSKis a command to check the file system and files on your disk. It can tell you about the drive health of your disk and filesystem.SFC[System File Checker] is a tool to correct Windows software in your OS by using a secured Windows Storage folder to get corrected versions for system files.
I would only use CHKDSK if I suspected disk errors; my vendor hardware diagnostics tell me my drives are fine, so I do not CHKSDSK.
I run SFC, preceded by DISM, on Windows 10 if I experience strange things or errors, as DISM and SFC have some ability to correct such errors.
