In my experience it is typically easier and more fun (for all parties involved) to keep the team together as much as possible, moving as a team. Magicians can provide magical support without using astral projection and they can also view the astral plane while still having control of their meat body by using astral perception. Technology specialists (such as Riggers, Drone Operators and Hackers, etc) can provide matrix firewall defense by slaving team member PANs to theirs and they can wireless control their vehicles, drones or hack networks around them while still having control of their meat body (by using augmented reality rather than virtual reality). The components and the rules are all there to support this. But what if the teams more squishy members must to go rag-doll-mode (or take a bullet to the knee and can't walk anymore)? Well.. that is perhaps why the team's tusker should not skip out on his strength attribute ;-)
But with a skilled GM to facilitate the experience it is also possible to split the team up. You need to quite frequently switch scenes though (similar to how they would film an action movie with multiple heroes working towards the same goal but are at different locations). Of the archetypes you mentioned the Face is often skilled at social infiltration (fast talk, seduction, impersonating, performance, directing, commanding, intimidating, etc) while the Sam is typically skilled at physical infiltration (sneaking, hiding, climbing, crawling, jumping, hand to hand combat, silenced take-downs, etc) which open up a few options for the players how they want to infiltrate. The others can take on a more remote supporting role. You could for example have a magician in astral space scouting the place out, instructing their spirits and manifesting to communicate to their teammates on the physical plane even though their meat body is actually miles away. The rigger's meat body could be located in a rigger's cocoon in a van that is driving around in the neighborhood on auto pilot a few km away while his mind is jumped into a combat helicopter or surveillance drone to provide support or a possible extraction in the meat world for the rest of the team. Maybe the hacker is laying unconscious in the back of the same van while hacking the facilities network via hot-sim to control cameras, sensors, elevators, alarms etc to make the infiltration go smooth. The team's sniper (which seem to be a popular fantasy that is also often "remote") is perhaps located on the roof across the road providing overwatch with his .50 cal sniper rifle in case the shit hits the fan. etc.
