Hardtail Build Advice

Looking for suggestions on my build plan and components. What should I put on this titanium frame?

I'm about to start my first bike build. Most of my riding experience of late has been road/gravel, with hydraulic brakes and electronic shifting. I want a more versatile ride that is a good fit for routes with some single track. Since some of my routes may be long and remote, I'm planning to go old-school (cable disc brakes and cable shifting) for ease of repair. I favor SRAM. Would consider Shimano. Here's my component plan:
