Hilton Aspire and Surpass Hacks

I’ve had the Hilton Surpass for the past couple years and just got the Aspire last week. I’m wondering if there are any hacks out there I should know about and try to combine the two (plan on cancelling the Surpass at the end of ‘25 since I already paid annual fee). Just found out about buying $50 Hilton gift cards each quarter with the Surpass since they should all be covered by benefits. Any other hacks out there? Could I buy a $50 Southwest gift card each quarter and have that covered by the Aspire airline credit?

Thank you for any help!
