No you don’t get any priority at your home resort. Now obviously if you waitlist during your 7-11 month window, then you will be higher up the waitlist than someone who has a different home resort, since they cannot waitlist until the 7 month mark.
However your whole waitlist needs to be fulfilled at once, so someone below you on the list may jump ahead.
Example, the BLT waitlist might look like this (nights requested shown)
A - wants Mon thru Sat
B - wants Tues
B - wants Wed
C - wants Fri & Sat
D - wants Mon thru Wed
Someone cancels and releases Wed thru Sat.
A needs extra nights that are not available, so doesn’t get any.
B will get Wed night.
C will get Fri & Sat
Thurs is still untaken, so returns to the RAT (resort availability tool).
A and D remain on the waitlist. So does B for the Tuesday night.
So you need to think carefully about what to request. If you just need two nights but need both or none, then you could waitlist 2 nights at different room categories, different room sizes or different resorts.
If you must be in a standard studio at BWV, then you would likely waitlist each night separately.
