In general a group is used for channels that use similar processing or treatment together. In analog consoles without VCA’s they are used as you want to do. If you just need level control groups, you may consider using DCA’s for that purpose. Then if you want to mute all those instruments or vocals you just mute the DCA that controls those. If you need common compression or EQ then you might consider using a group.
A matrix is commonly used for outputs feeding other parts of a venue different from the main mix such as front fills, out fills or even other rooms that need a somewhat different mix that the main room. It takes input from the groups and main and even aux’s in the case of the iLive system. This will allow say less instruments in a front fill mix that’s close to the stage etc.
That’s why they function the way they do. There can be other unusual situations that require novel routing but this is the basics.
You can do a lot of control with the DCA’s, just be aware that they will affect any auxes for channels if they’re set post fade.
Hope this helps a bit!
