Essential accessories for a Lumix S5II L-mount camera setup?

Question

So I finally pulled the trigger on the S5II after years of being a GH5 diehard and honestly I'm kind of freaking out. I love the phase detect, its a total game changer compared to the old contrast based hunting but man the accessories situation is stressing me out way more than it should. I know the basics of videography but moving to full frame L-mount feels like I'm relearning what fits with what all over again.

I have this huge wedding shoot coming up in rural Vermont in about three weeks and I realized I basically have nothing for the L-mount system yet. My logic was that I could just use my old EF glass with a Sigma MC-21 adapter but now I'm reading that native glass is way better for the AF tracking and I'm wondering if I should just bite the bullet on a 24-105 f4 or something. But then there's the battery situation. These new batteries seem to drain way faster than the GH5 ones especially when shooting 6K open gate which is what I want to do. I was looking at those SmallRig cages but then do I really need the top handle or should I just stick to a side handle for stability? My budget is super tight now since I blew most of it on the body and a 50mm prime, maybe like $500 max left for everything else.

I'm worried about the cold in Vermont killing the batteries even faster. Here's what I'm currently debating:

Official Panasonic batteries vs third party like Wasabi or Neewer

V60 vs V90 SD cards (can I get away with V60 for 10-bit 422?)

A decent monitor because the built-in screen is kinda small for my old eyes

Whether a cage is even necessary if I'm mostly handheld

My logic says I should prioritize power and storage but I'm terrified of the camera overheating or failing because I cheaped out on a dummy battery or something. I really cant have this thing die mid-ceremony. I'm just spiraling a bit trying to make sure I dont miss some must-have thing that everyone knows about except me since this is my first real full frame setup. What am I missing to make this thing actually field-ready for an 8 hour day...

honestly you can totally skip the v90 cards. the s5ii maxes out at 200mbps for the 10-bit 422 stuff so a Lexar Professional 1667x 128GB SDXC UHS-II Card will handle it easily without the v90 price tag. for the Vermont cold, definitely keep your spare batteries in an inside jacket pocket against your body heat to prevent voltage drops. if your eyes are hurting, grab a Feelworld F6 Plus 5.5 Inch Touchscreen Monitor. it is super budget friendly and makes pulling focus way easier than the tiny back screen. since you have that mc-21 maybe just use it for your telephoto needs and pick up a used Panasonic Lumix S 20-60mm f3.5-5.6 L-Mount Lens for your wide shots. native glass is just way stickier for tracking movement during the aisle walk. keep it simple and dont overthink the cage if you're trying to stay light and mobile. the ibis on this thing is basically magic anyway.

Regarding what #3 said about "honestly you can totally skip the v90 cards...."

I've found that too, but are you planning to shoot the ceremony handheld or on a gimbal? In my experience, the cold in Vermont will basically tank your battery life faster than you think. I'd really recommend the Panasonic DMW-BGS5 Battery Grip tbh because it lets you hot-swap without killing the recording. For a wedding, that extra security is worth every penny so you dont miss anything.

Over the years, Ive seen generic batteries fail in the cold. Stick with Panasonic DMW-BLK22 2200mAh Lithium-Ion Battery. Also, ProGrade Digital SDXC UHS-II V60 Gold 128GB Memory Card handles 10-bit files perfectly.
