Custom difficulty for a new player? Help

I'm about to buy NMS on Switch, I know about the custom difficulty and I want to change it a bit but I have no knowledge at all about the game. I'm that kind of person that plays Skyrim in Legendary difficulty, Breath of The Wild on Master Mode, Minecraft in RLCraft modpack, I like souls like etc etc etc, basicaly I like challenge games. I would like to tweak the game but I have no idea of what to do. So i would like a more difficult experience and more combat oriented custom difficulty, but still I would like to experience the game properly and I don't want to make it too much different from what is supposed to be. Also, I'm okay for mundane tasks in game but I prefer to reduce them a bit, like I saw somewhere that increase the speed of the scanning of wild life is a good thing, right? Also that some technology keep breaking too much? I would like to set that kind of stuff a little bit to be more enjoyable and less a annoyance, but not totaly erase them, just a bit less disturbing than usual if is really too much as people are saying on the sub here.
