If you are using macOS 10.13 or later, you'll also see an option named APFS, which is the default file system of macOS 10.13 and later.
1APFS (Apple File System)
APFS is a new file system for macOS. It's the most appropriate format for SSD. However, you need the latest macOS to write to this file system. If you're sure that you don't need to use it on a Mac running old version in the future, then you can format your USB drive to APFS.
2Mac OS X Extended (Journaled) & Mac OS X Extended (Case-sensitive, Journaled)
Mac OS X Extended, aka HFS+, is the default file system before APFS for macOS 10.12 and earlier. It doesn't put a limit on the size of files you can save on the drive, which is the greatest advantage. Windows-running computers can read the files formatted to Mac OS X Extended but can't write to them. And this file system is necessary if you plan on using the drive for Time Machine backups.
The biggest difference between Mac OS X Extended (Journaled) and Mac OS X Extended (Case-sensitive, Journaled) is the latter one is case-sensitive to folder names. For example, 'file' is different from 'File'. Therefore, if you do not have special needs, just ignore this option.

These two are basically the same with the previous two but with encryption, which means you have to provide the password whenever you connect the drive to your Mac.
4MS-DOS (FAT)
This is Disk Utility's name for FAT32 file system. As the most widely compatible file system, it suits both Windows operating system and macOS. Therefore one can easily transfer data between PC and Mac using a USB drive formatted this way. However, a USB drive formatted to FAT32 doesn't support long file names and an individual file cannot be larger than 4GB.
