Had Sturmey Archer Drum brakes on one bike for 25 years, the brakes needed zero Service.

because the drum shoe has so much surface, on a bike , its wear is un noticeable ..

SA drum , IGH might need a few drops of oil in the gearbox every once in a while .

3, 5 and an 8speed (8speed the chainring would be tiny , since the 1st gear is the direct one

The other 7 are overdrive gears, so what you want for Low gear is the crankset chainring)
