How to determin the load requirement for 24V DC power supply
The fuse is redundant for the supply you chose which already has active OVP and OCP, but may have been useful for a much bigger previous supply.   You may wish to add decoupling caps to end device loads if you suspect inductive noise currents.  Sensors in particular may be prone to shared  conduction noise with solenoid or motors. Otherwise cable wiring needs to consider ambient noise for compatibility (EMC) and possibly require shielded STP cables grounded only at source.

I don’t see any PSU issues but choice of earth grounding to 0Vdc must be based on noise immunity (EMC) requirements.
