Seeking advice: New lens: Nikon 105 f2 DC or Fuji 90 f2

I am fairly new to Fuji. I have an X-T1 (coming from Nikon film for the past two years: N90S, which I still own and use; yes, I am just getting into digital). I own the following lenses: Fuji 23 f2, Nikon 50 f1.8, Nikon 135 f3.5, and Nikon 80-200 f4.5. Then I have a speed booster so that I can use my Nikon lenses on my Fuji.

I just got started working as a professional artist, specializing in painting, drawing, and illustration (sometimes sculpture, but mostly for fun). My photography informs that work and other than that I shoot portraits and landscapes and abstracts for fun.

I would like to buy a new lens and it makes sense to buy the Fuji 90mm, but I have always wanted to buy the Nikon 105mm f2 DC. I cannot buy both. I am comfortable using manual focus, because that is all I have used. So, I am looking for some advice.

Would the Nikon be a better "investment" lens (as in re-sale value)?

Is the Nikon lens so great that it would make sense over buying a lens that is specifically designed for my X-T1?

I am looking to invest in a quality portrait lens. Do you have other suggestions?

I look forward to your responses and thank you for taking the time to read my post.

If you will only shoot in manual I don't see the point in getting the Fuji 90mm when you can find the Nikon for less than $700.  I have it and it is a beautiful fun lens, on FF.  Keep in mind that 105mm on APS-C will be very tight, so if you have plenty of space to use this prime lens then go for it otherwise a 50 or 85 1.4 might be better for you.

Having said that, me personally, I don't like using manual focus lenses on Fuji bodies and it is definitely better to use Fuji lenses instead for full optimum IQ performance.

In fact, if you want to shoot in manual save more money and get Samyang lenses that already come in Fuji mount.
