Best mods for someone new to the game?

Hello! I’m newish to Factorio (200 or so hours) and I was wondering what mods might be good for someone looking to enhance the base experience of the game. I don’t want mods that simply just add content to add it, but rather things to make the experience smoother/less of a pain (minor content additions are fine). There’s two mods I know of that accomplish part of this and that’s the small machines and the walk through gaps mods (names aren’t my strong suit currently). Any recommendations?
