Death, any X body will fill your photographic needs, but in my opinion, the X-Pro 3 is pro-tough and likely your best choice to live a 10 year tough environment pro life.
While I never compared, publications say the Fujifilm JPEG's SOOC are a cut above other brands because of Fujifilm's history of film chemistry and color science. I now believe this, as I recently went exploring film simulations and image quality adjustments. The control over a finished image using these features is surprisingly comprehensive and really impressive. If I did pro work, I would shoot JPEG+RAW, but as an amateur, I may never shoot RAW again.
I just did a deep dive on lenses, and was really impressed with the 27 mm pancake lens. It was great for literally any purpose. Its versatility is noteworthy. The 35 mm f/1.4 was an awesome lens, but the 35 mm f/2 really wasn't far behind. It's much smaller, lighter, and less expensive than the 1.4. If I didn't already have a 35 mm f/2, I'd buy the 27 mm in a heartbeat. As far as a zoom goes, the choices are many. If you are considering a general purpose zoom for just the occasional shot, I was shocked at how good the lowly (and tiny) XC15-45 is for this purpose. If you are looking for more zoom quality, the XF10-24, XF16-55, and XF16-80 are all great. No compromises in image quality with them. Bigger, heavier, and more expensive, though. I know little of the Laowa except it gets good reviews. I don't think any of these are natively macro, but I use extension tubes with my 35 mm f/2, and the results are more than satisfactory for me - I mean *really* sharp.
