Wilson should be the most newbie friendly character. but not so mechanic intense. His beard is a great example for this since it give newbies a way to survive the 1st ingame challenge (aside from the first night, hi Charlie!) which is winter I would probbably add:
Start game with the knowledge to craft meat effigy.
Able to craft Red Potions with spider gland and berries (heals 40 hp over 2 mins). Drinking the potion will make his beard grow 1 tier. Wilson Starts the game with 1 Potion :3
Whenever Wilson Craft something one of it's ingredients will randomly drop. (Scrappy scientist)
These two coupled with op beard would make him a really good character for new player
