Choice for me would be between 18 and 23 – if you like wider, then 18, if you like slightly narrower, 23. The 18 is a great lens, maybe not as sharp or contrasty as the newer Fuji lenses, but super sweet rendering, especially out of focus areas.

The 7Artisan 35/1.2 is a nice lens, tiny and therefore handling is a bit awkward. I sold mine again, it just didn't get me much over the 35/1.4. I don't know the other 7Artisan lenses, so can't speak for these. I had the 23/2 and sold it again. Nice size, but it's a bit wider than I'd like for a 23 (it's more like 21) and the OoF rendering just isn't what I came to expect having the 23/1.4 – even at f/2 the larger, faster lens is just so much nicer rendering (to my eye).
I would not pick the Samyang for your use case, it's just too wide and slow, although it could be fun. I'm using the XF14 for fun shots of people, but they are rather rare.
My recommendation for what you describe is the XF1 18mm f/2, that's partly because I feel you'd want a greater distance from the XF 35mm and partly because I really like the 18.
