Tips for new Osmo Action 6 owner?

I only have an iPhone 17 Pro Max and just got the Osmo Action 6. I’ve heard it’s best to transfer video directly from the camera or an SD card rather than doing the WiFi transfer to the Mimo app. I just got a USB C hub so I can transfer from the camera to an external SSD using my iPhone. While it will work, I’m contemplating buying an iPad Air M3 or newer or a M1 MacBook Air to edit and color grade. Any suggestions on which I should get? Or just stick with my iPhone 17 Pro Max? I’m mainly going to be creating vlogs and videos to upload to Tik Tok or YouTube. TIA
