There are many odd cases that require you to have both standard screwdrivers, long bits and short bits. Most common issue I run into, mostly with electrical, is that the long bits don't fit right into a deep recessed hole (the shaft of the bit being too thick/too short). So in that regard, you already need at bare minimum flat drivers, but since flat is shit, you'll also want posidrive and philips, electrical mostly being posi.
Then the second common issue is that you just can't fit anything into a tight spot, so you either need an ultra low profile bit driver with the short bits, or a short screwdriver. If you're working in a hard to reach spot, the regular short screwdriver is likely gonna be less fiddly.
So basically, you need to have everything, but you can lean more into bits for special/security screw types at least.
