Filtering the list for linux will only show games with native versions. As far as I know, Satisfactory doesn't have one so you will have to use proton. Go into the steam settings and enable proton for all games. Or if you don't want to enable it for your whole library, go into the game settings in your steam library and activate it for each game.

Pretty sure there is a setting for it.

That's because you get an error a lot of times if you use proton-ge or wine-ge in lutris or bottles when installing. The trick is to use system wine for installing and then switching to wine-ge when the install is done.

IMO, just ignore the grading system and have fun. Once you're hooked enough and actually want to improve, that's when you will want to start paying attention to it.
