One way to increase the octane rating is by... adding ethanol.
So, take the lowest suitable RON number you can find. There is no
benefit to use higher octane ratings than the engine needs. The higher
the octane rating, the higher chance that the fuel contains ethanol, or
other similar unwanted additives.
I always use Euro 95 fuel, and never experienced any problems with it.
