Looking for a list of compatibility for 360 Cameras in Premiere

I'm looking for a compatibility list, recommendations, or advice on professional 360 cameras, in the market of 3,000 - $6,000.  I've found the stitching process to be the biggest pain point. GoPro's Fusion Studio is not reliable with the fusion 360 footage: it crashes regularly, doesn't import large videos that the device is capable of shooting and can be viewed unstiched, and the UI doesn't behave on my machine.  And its still honestly the best stitching software I've used.  I haven't spent much time with 360 footage in the last year or so before this fusion footage fell into my lap, so maybe the process is easier then I'm making it out to be now.  I'm looking at purchasing a camera at the $3,000-$5,000 for studio usage, and at that price point I want to ensure good results and hopefully less pain for myself.  The Insta360 Pro II Spherical VR 360 8K Camera claims that it can stitch internally for Premiere, though I believe it only does MP4 format.  I would much rather have a 6K or 4K Flat Log to work with over 8K, but I'm not sure if RAW codecs are available with any cameras on the market.  At the end of the day, I'm really looking for the least painful stitching process into Premiere though.
