I'd probably do either the aws or azure architecture exams. I use both fairly often but have a bit of a gap on the infrastructure side. Alternatively I might do some actual building in serverless technologies rather than just drawing pictures, I'm at a large company so often developers are picking up the detailed tasks.

If I wanted to do something completely new I might dive into more detail around security/pen testing although I've noticed that a lot of companies doing this just seem to run a lot of off the shelf tools these days.
