The only way to be sure of the content you are formatting is to first remove the USB drive from Mac, know the title of other storage disks, insert the USB disk again and note the name of the disk. Now you are sure not to be formatting a wrong disk this way. Next, drag the USB data to a safe location for backup/recovery measures before formatting it. Then you are set to get it done!
For PCs operating on macOS High Sierra or newer version, you can select from two options of file formats: Mac OS Extended and APFS. Here is the difference, APFS format is not compatible with macOS versions older than High Sierra. Therefore, if you are sure to still insert your USB driver on older versions of macOS, then you should consider formatting as Mac OS Extended.
Also, if you are to use the USB drive as a destination for Time Machine, you should consider reformatting to Mac OS Extended as Time Machine cannot back up an APFS disk.
