Pros and cons of centralised vs decentralised power deliver for small devices
Distributing 5 V or 12 V can be smart if the currents are low enough (much less than 100 mA for example) so voltage drop isn't an issue. But an RPi already exceeds that.

Other things to consider:

Reliability, if everything is running on that 24 V and it breaks, nothing works. If you use a mains adapter for each device, the risk is more spread out. Also you might have a spare adapter available or swap an adapter until you have replaced the faulty one.

Efficiency, the 24 Adapter will need to power everything at full load. That might mean it is much less efficient at lower loads. Compare with PC power supplies, these can deliver a lot of power but often only reach their rated efficiency when loaded with at  least 60 % of their maximum load.

In my opinion, unless you have many low-power devices, using a 24 V distributed power is not worth the trouble.
