m_lance, sorry to hear about your silver x100 F has this issue. As you can see from above, I went through 3 units before I found one that had the RCD operating properly.  Both the units I returned were within the merchant's 30-day return period. I hope you're able to get yours repaired/replaced under the Fujifilm 1-year warranty.

I've compared this behavior on the x100 F of the Rear Command Dial (RCD) versus the xpro 2. The xpro 2 scrolls easily within the options of the highlighted Q-Menu option without any accidental press of the RCD. It takes a deliberate press of the RCD to make a selection. 

In case useful to others, I've mapped the EXIF info for the various film simulations offered by the Fuji X100F.
 
You need to read 2 tags (FilmMode and Saturation) to get the full information. 
I've used exiftool, a command-line tool, to get this. I am on a Mac but exiftool is freely available on most platforms.
 
(Now if someone could find out whether whether usage of the built-in ND filter is captured in EXIF...)

I used to keep the boxes, but space became a problem. What I do is cut out and keep the box panels (sides) on the box that show the model and serial number etc. This way I can document that these are original items.   I store the cut box panels in zip lock bags along with any manuals or other documentation. All of these zip lock bags are kept in a plastic covered box (Rubbermaid). I can fit bags for multiple camera bodies and nearly a dozen lenses all together until I sell an item.    
When I sell an item, I pack the lens or camera body securely myself (nothing moves or slides around), add the zip lock bag and send it off.

On the two conversions lenses (WCL-X100 & TCL-X100): I find the quality and sharpness in my use very good to great when using them for what a family- or enthusiast-photographer might photograph. If you are a fine art photographer, you could still use these, but you would get ultimate sharpness and quality with Fuji's prime & zoom lenses for their  interchangeable lens cameras (X-T1, XPro1, XE-2, etc.). 
 
There are lots of reviews out there about these conversion lenses from both review sites and user reviews. Links below are to two reviews from Imaging Resource. I included them not because they are definitive, but because they'll give you a good feel for the lenses and how they might work for you.

For me, the X100T is a great camera to carry and use with a flexible field of view (35mm equivalent). I use both the OVF and the EVF and love having the option of the OVF. I haven't use a Canon Rebel, but I assume they have an OVF, so the X100T's OVF should feel comfortable in use and with the EVF available, you can either transition to using that or switch between the two (as I do) as your shooting situation warrants.
 
The two conversion lenses extend this capability, allowing you to buy the X100T now and, if needed, add the conversion lens or lenses later, all while have a small, light weight kit to carry around.
 
The thing I ask myself when I go out the door (or when I'm packing to travel somewhere) is: how much am I willing to carry?
 
Hope this helps.
