Tiagra 10 speed shifters & compact crank. XT rear mech & CX front mech. 12? /32 cassette. All play very well together on my commuter / gravel bike.
Tiagra 4600, the older version, should work fine.
The new 4700, not so much.
Both are 10 speed. The OP is considering mixing the 4700 one with MTB RDs.
