Moving to SN+ oil is your first goal. Because if you don't, then the problem of LSPI-inducing oil particles remains. The next thing is to keep the injectors clean, since it affects spray patterns and cylinder wall spatter. It was found that rotating the injector 45 degrees would increase wall spatter, so imagine the smooth flow of fuel interrupted by deposits making the spray go willy nilly ... Again, not to alarm, just to make aware. I do not know how big an issue the deposits are. Every aspect is being researched, but not much quantification by way of importance, other than oil first, fuel second.
I have not yet begun to research what fuel will help with that. Tho I do know there is VERY little research on current fuel additives like Techron/BG in DI situations. There is supposedly a custom additive proven to reduce/eliminate fuel injector deposits, but I cannot find it on the open market.
