That depends on many things including the type of services and events, the shape of the room, sightlines, what all is on stage, whether you have any rigging, the budget and many more.
In a traditional music performance space the volume is critical for acoustics, but as you move away from natural reinforcement from the room and towards the audio systems providing all the reinforcement then this becomes less critical. In cases where there is high SPL audio but congregational interaction is important a very high ceiling may be counterproductive.
Quite often there is difficulty fitting appropriately sized video screens, so that may be a good place to start looking. People often forget that you need to account for the stage height plus the height of the performers and set pieces and then some room to make sure rigging, lights, speakers, etc. clear the screen along with the height of the screen itself. This often defines a minimum desired height at the stage.
Construction budget will obviously also be a big factor. Taller spaces can be expensive to build and maintain.
Hopefully whomever is designing the systems will work with your Architect to help on this.
