Capture One Express for Fuji is free and quite capable. I use the paid version personally, but the free version covers most needs if you don't batch process and don't mind not being able to make your own styles.
Only 2 lenses? 10-24 and 55-200 would be my choices. But I'm a landscape/nature shooter who hikes, as much as I love primes if limited to two lenses I'd have to go with those.
For a second lens to pair with the 23/1.4, I'd pair the 56mm f1.2 for sure.
Brand new cameras tend to end up with a flurry of firmware updates for bug fixes, once it gets some time out there things will settle down although Fuji tends to release more firmware updates than other makers, adding capabilities and updating to improve older bodies performance with newer lens releases.
The X-T4 is very new and still in the bug fix mode.
The X-H1 was actually much worse for that when new, but has been around long enough to mature.
Options two and three are really good ways to go. I never cared for option one for the reasons mawz mentions.
Also, keep in mind that sunset, sunrise shots in general tend to look well with the contrast between color and dark.
