What format HDD for PC

What format is compatible with PC? I am trying to sell my old external hard drive. Using disk utility on my M1 iMac I have a choice of: APFS, AFPS (encrypted), AFPS (case-sensitive), AFPS (case- sensitive, encrypted), Mac OS Extended (journaled), Mac OS Extended (case-sensitive, journaled), MS-DOS (FAT) OR EXFAT. Which format please?

thanks in advance.
