HA Yellow v Docker

I’m currently running HA in a docker container on a Synology DS718+. I have lots of integrations and many ESPHome devices. I should be moving home in a few months and will basically need to almost start from scratch. I’ve been considering whether it would be worth moving over to a HA Yellow but have a few questions:-

Would it run quicker on Yellow with a decent RP4 and SSD?
Can I run ESPHome on the yellow (currently in a docker container also)?
Is accessing my yaml files straight forward on a yellow?
are there any pitfalls or other that I need to be aware of?
Will it be an upgrade?
Many thanks
