New to PC

I’ve always played the game on console - PS4 when it originally came out, then PS5 up until today - I bought a gaming PC

Just a couple questions because I’m excited to pick it up.

There was a mod that I’ve read about that makes the e game have RPG elements. I know people have differing opinions, but is this one I should try out first? If not, what would you recommend?

Do any of you use controller when playing on PC, or does it only really make sense to play with mouse and keyboard?

Any other mods I should install.

Thanks - I’m sure all this has been answered before, just wondering if there’s been any change in opinion.
