Resolve + Mac Pro setup

Hi Everyone, Happy (nearly) post-pandemic.
My trash can Mac Pro has a thunderbolt bus dying-- rather than go through that mess (again), I bought a used 2019 Mac Pro. It saved thousands off list, for which I am grateful, but it still ran about $9500 after shipping and tax.
16-core processor (32 threads) 96Gb RAM, 4Tb, Radeon 580x.
I will likely expand the RAM and add the Afterburner card since I cut exclusively in ProRes. But I know nothing about video cards, at least modern ones.
What is a great video card setup for this Mac for Resolve and After Effects? I use particles A LOT, mostly in AE with Particular. I do some stuff in the Fusion page, but nodes are a slow learn for an old AE layer hacker like me.
Higher resolutions aren't a concern, I deal mostly in 1080p, occasionally 4k, but I try to stick 1080 to save drive space. I never deal with anything over 4k.
Thanks for your thoughts.
