I have the 100-500 for my R5 and it's magnificent! The R5 allows a ~1.5 crop and the 100-500 stands up to it. I don't need to really consider an APS-C extender body any more but I have the 1.4x if needed. The 100-500 fits my airline travel camera pack and the weight is still manageable on my old body. I've been doing digital travel wildlife photography for over 20 years now and the IQ from the R5 + 100-500 is a noticeable improvement over my 5D4 + 100-400 L. It's the right general purpose wildlife lens.
I haven't used the 200-800 and assume it's good. But it's big and heavy by comparison. For dedicated specialized use its probably fine, but the 100-500 is the general choice in my opinion.
