Nowadays many designers will avoid electrolytics are far as possible. Still need a few critical ones in switchmode PSUs but the vast majority of coupling and decoupling can be done with ceramics. 100uF low voltage ceramics are cheap and plentiful. Higher values are available. They're not the most wonderful of caps, with wide tolerances and C depending on applied voltage. But then electrolytics are hardly wonderful either.
