First, thanks for this great post there's a lot of great info in here! I've got a 350mhz ceiling fan that I'm looking to integrate with Home Assistant/ESPHome and this has been a great resource. Currently, I just have an esp32 running esphome soldered to a spare remote and it just "presses" the buttons using optoisolators. It works, but it's a bit slow and unreliable. In your post, you mention that you needed 350mhz, but the example code you only show the 433.92mhz remote. Did you ever get the 350 to work? From what I can see, the CC1101 doesn't support 350mhz.
