I pick up XT's whenever I find them. So I guess I'm already in that one derailleur space.

Lotsa neat derailleurs here, for sure. But how many of them, even the Campys, would you really want to have as the only rear derailleur you could ride on all of your bikes for the rest of your life?
I mean, I adore the 1980 Superbe I've got on my Fuji. Light, beautiful, shifts better than I do. But there ain't many of 'em around anymore, so equipping an N+n of bikes with them would be difficult. And do I really want to be limited to a 26t in back... on every bike forever?
No.
And that's why I think that a 7-9 speed, Deore-or-better, long cage Shimano mountain bike derailleur is the correct answer to the question.

Pretty sad day in the land of C&V if your ONE & ONLY rear derailleur is Deore. (Recall the op—supply is unlimited in quantity)

It's like asking what shoe you would wear if you only had one choice.

WOW
You did take me off my guard!
I didn't expect to see Sun Tour's Skitter on the internet at all.
I haven't used Skitter, but used Shimano' Skylark.
They both are steel rear mechs.
They don't bend when pulled and shifted.
So they shift sweeter than modern aluminum mechs.
Thanks for the photo!

With you on the Crane
Both versions are very nice

I would really like to say NR is my favorite because it’s so good looking. VeloBase shows a long cage version like this but I’m not sure if this might be Frankenpiece with a Rally cage - I just got this one but I think I have another somewhere.

My favorite (C&V-wise) though would have to be the DuoPar - very smooth, sure, and quiet. I’ve heard that they can be prone to twisting into spokes but never experienced it in 40 years of running them.

The Super Succes has titanium bits, a 24/28 cage attachment option and ball-bearing pulleys, which you can overhaul easily if you have little smurf hands. Grey color is a bit dull, I wonder if anybody ever mated a drilled 'Super' cage to one of the ordinary Successes in stealth black, that must have looked better than super.

I'd have to go w/ Suntour XC pro. Beat the be-jesus outta it for over 30 years on a couple Mtn. bikes and it still shifts like the day it was new.

I am frugal, so I would select a SunTour VGT Luxe.

I have to say that in my opinion, that Suntour Cyclone is the finest non-indexed derailleur that I have used. That said, I really do like indexing, so I would probably say that I would want either a Shimano or Campy 9/10 speed unit, long cage.
Well, I think that from a vintage point of view (friction) it's just about impossible to beat the Suntour Cyclone, 1st generation -- either the short or long cage version. s
I'm no indexing expert, but the Shimano RD-M739 (Deore XT) was very classy looking, and functional, plus it will deal with a lot of teeth and big cogs.
There are a lot of front derailleurs that can work; it's a much simpler operation. So choose based on looks alone.

For me, Shimano XTR M953 SGS. Rapid Rise all the way!

Or if they're not available, a close second for me is the Deore LX Rapid Rise version:

I was going to say this--the M950/952 is hands-down my favorite friction shifter for any bike that doesn't need something specific for that just-so look. I can also confirm that, depending on the length of your hanger, it will shift to 36T without an adapter of any sort (my Black Mountain Cycles Road is running a 46/30 chainring with a 12-36 10sp cassette for 'ride-over-anything' capabilities, and this derailleur handles it like a champ), and I use a Wolf Tooth Road Link for a gravelish bike that is running a 36T 1x with an 11-42T cassette.
