Anyone have ideas for test shoots?

I've been modeling as a hobby for a bit and am now trying to go for it full time. I've started reaching out to photographers for test shoots/TFP. I'm used to the concept, outfits, poses, etc. already being laid out and I model. But a lot of these photographers ask me what I want to do and what I need for my book/portfolio. The thing is... I don't know what I need. I'm not sure what agencies/jobs are looking for.

Any ideas for test shoots I should 100% have in my book?

Pinterest boards appreciated 🙏
