Flight HNL->DFW (late september)

I have available BXP1 certs, which I tried to apply and seem to have been waitlisted.
Currently no C inventory on EF, seems like the HNL->DFW flight only opens up a day or two before the flight presuming that business inventory "J" i think still exists.

I've been told by EXP Desk that Mile and Cash are equivalent to BXP1. From everything im reading I don't know that to be the case

1. EXP Complimentary Upgrade
2. Miles + Cash Upgrade
3. BXP1

It seems like BXP1, up until 24 hours in advance, is the best way to go.
Should I withdraw it after T-24?

can someone confirm I am looking at this correctly? IE is an EXP w BXP1, vs a EXP with miles and Cash upgrade higher?
Also I am traveling with my wife a standard member of AAdvantage (no status), on same PNR, lmk if that affects the answer


thanks
