What is the best/fastest way to host a wappler site on AWS or GCloud (not firebase). Could I use docker? or would a more traditional LAMP or similar be better? I will try out the newly added firebase.

For AWS your u can follow their tutorials indeed for creating a LAMP server or using docker.

We have also included them as reference when using Amazon RDS

We do prefer digital ocean and have it much better integrated in Wappler when using docker. But of course you can do the same with AWS
