I’ve found one of iFixit’s comprehensive bit sets to be highly valuable in responding to random repairs where manufacturers have included an odd security screw or two to make something harder to repair.
That can make the difference of a simple part-replacement repair being possible for most people who would otherwise easily have access to chunky flathead & Philips head screwdrivers suitable for furniture.
As for torx drivers, unless you can find some made from the finest tool steel on the market, I’d suggest sticking to replaceable bits and bit-drivers, because when the public have hold of those drivers, somebody will eventually round off the teeth on a seized-up or off-sized screw, especially on the fine blades of small torx sizes.
(This lesson was learned from many years of operation in a local social enterprise with plenty of well-meaning volunteers using shared tools).
At that point, the fact that iFixit will sell replacement individual bits for their kits means that you can take the risk of people breaking bits into account, then replace those with donations from the clumsy, and avoid a lot of waste from otherwise potentially throwing away whole single-size screwdrivers.
(Although if that ever does come up, you can always take a rounded-off screwdriver and trim it back or grind it down to one of the simpler shapes on a grinding wheel).
If your users want to do bicycle repair, then a torque wrench is likely needed for those bigger bits.
