I'm wondering whether it makes more sense to deploy a traditional FAS architecture with a combination of Flash and traditional disks if I have a combination of workloads that require Flash as well as traditional disks, or should I be positioning AFF + FAS. In some cases when deploying VDI solutions, it makes sense to utilise Flash to optimise the gold images, but some data such as "home drives" don't demonstrate any scales of economy when deployed on an AFF. Am I misinterpreting this or is there a methodology to deploy an AFF + FAS?

You've got a few choices here for bringing flash into your deployment.
1. A single FAS array that has a combination of aggregate types e.g
If you are using Clustered Data ONTAP, it's easy to move your workloads between these aggregate types on the fly, and OnCommand performance advisor gives you plenty of data to help you make that decsion.
The big question is, whether you need an all flash node to host your all flash aggregates. In general I'm a big fan of the idea of having at least a pair of All Flash FAS nodes in your cluster for the following reasons
I hope this answers your question.
