I currently hold the plus and priemer card to get the CP from last year and this year due to the SUB involved. TBH, i recommend going straight to the priority card, it has a higher annual fee, however you are able to recoup it if you fly SW enough due to the travel credit and the bonus 7500 annivarsary points. In the end, the effective AF of the priority card is the same as the plus card with more benefits.
all three come with the 2000 CL needed for visa platinum and 5000 for VS, no difference in language there.
If you frequently use SW for your flying needs, then the Priority card would make the most sense since the $75 travel credit offsets the AF by half.
You will have to act soon to fully utilize the companion pass this year though.
