I own the 70-200 FL version, and have passed on some of the lenses you've mentioned. Here's my 2 cents.
First of all, if AF performance is a thing at all, the 70-200 FL beats them all. MF experience is great on the 70-200 too, unlike most other AF lenses that are abysmal when it comes to manual focusing.
Bokeh on the 70-200 FL is great, I love it. The Tamron 70-200mm G2 also has great bokeh and rendering, but it has quite severe focus breathing issues which is not found on the 70-200 FL. I would figure it's an annoyance at portrait distances.
For landscapes, you'd want a steady tripod, and preferably a replacement lens foot:

You own the 85mm, 105mm, 135mm, and 180mm D-series fast prime lenses. Which ones are your favourite? I sold my 180mm AF-D and dropped the 135mm f/2 DC from my list because it wasn't as good as the 105mm in terms of optics. The 85mm f/1.4 Zeiss classic and 105mm f/2 DC-nikkor were on my list a while ago, but I've forgotten about them altogether after purchasing the new 70-200mm FL.
My suggestion is to rent one for a week or so, and don't delete any photos. Load images and keep them in a program like lightroom, this allows you to see which focal length you are using the most. You may then base your decision off the sample you have. I absolutely love my 70-200 FL, and some may disagree, but it does have prime traits. I own an 85mm f/2.8 PC-E which is sharper than the 70-200mm at close focus distances, but both are plenty sharp.
I made this a while ago to illustrate the fact that different software handle files differently, it could be somewhat helpful here to exemplify the expected rendition of the 70-200 FL:
Nikon D810 Jpeg Fine VS LR Raw and C1 Raw Conversions by
Macro Cosmos (DH)Edit: I forgot to mention VR and the 4 programmable (somewhat) buttons on the 70-200 FL.
VR allows me to shoot at 200mm, 1/50 handheld. Not the best in the world and I know people who can easily do 1/20 with the right technique, but it's good enough for me.
The 4 buttons are indispensable. I have them programmed for AF and use them more than I use my back button for AF. Also note that the zoom and focus rings are reverted unlike conventional nikkor zooms. It took me... maybe 10 minutes to get used to it, so no big deal to me.
Cheers!
