PMK modes are for SSID-specific lookup tables (poor man's rainbow table) and are generally only useful in very specific circumstances.
PMKID is a slightly different attack on WPA that is generally more robust but does not work with every router. For more info see here: https://hashcat.net/forum/thread-7717.html
Don't use aircrack. hcxtools are much more robust for capturing and extracting relevant data.
hccap is old and deprecated, a successor format is hccapx. The next stable version of hashcat (>5.1.0) will replace hccapx with a text-based format.
