3) Intel platforms are slightly better for encoding H.264 source media to H.264 (and presumably also for H.265 -> H.265) since they have Intel Quicksync which helps accelerate decoding of the source footage. It is significant enough that on our tests with H.264 source media, the Intel Core i5 10600K 6 Core was often as fast or faster than the AMD Threadripper 3970X 32 Core. This means that if you work with a lot of H.264/H.265 media and want to minimize export times, you should stick with an Intel-based system with Quicksync - at least until Adobe adds GPU-based H.264/H.265 decoding.
