I don't believe you're doing anything wrong, because I have the same issue. The only thing the function button allows you to do is switching face/eye recognition on of off. No more options. My X-T2 did offer the option to switch between auto eye, left eye and right eye detection, but the X-T3 sadly not (Fuji are you listening?). Now you have to dig into the menu setting to make the required settings.

Recent versions of Lightroom have the option of using the film simulation used when capturing the image. It can be changed. Go to Lightroom > preferences. Look for the tab Presets. Here you can change the settings. You may even do so per camera used. There are three options: any preset to your liking, or Adobe Standard (instead of the horrible Adobe Color) or Camera Settings (your used Film setting). Hope this helps.
