If you want no grain, shoot Astia (RMS 7, finest grain slide film).
Grain-wise Velvia 50 and Velvia 100F are nearly indistinguishable as
far as I can tell (RMS 8 vs 9). Note that Velvia 100 (not F) is also
RMS 8.
But I like grain. Which is why I shoot Tri-X pushed to 1600+.
I shoot a lot of Delta 3200, so I see you there.
I'm not suggesting that I am looking for the finest grain. When did
Velvia 100 non-F launch? I was running my lab until May and at that
point we had heard nothing about it -- was it late summer? I have to
wonder what the point is of such a film -- they didn't keep dual
inventory of Provia 100 F and non-F nor Astia 100 F and non-F.
Annouced June-ish, started showing up in August/September. Dual lines
happened because 50 was simply THE standard landscape emulsion for so long.
My own tests comparing Velvia 100F to old Velvia 50 didn't yield a
significant difference in contrast or saturation, though they were
checker-chart and skin tone tests under sunlight and strobe rather than
real-world images (mostly done to check comparative processing times --
E-6 is pretty flaky as a standard these days, with every manufacturer's
own E-6 equivalent seemingly designed to make the other guy's film look
bad -- and I'm going from memory, but I think I ran the 100F a little
longer in the colour developer than the 50). Is there perhaps an online
comparison that someone has done?

I'm surprised you didn't see a difference, but it could be the subjects
you checked. 100F is distinctly less saturated than 100 or 50 (This is
the reason they introduced 100, because 100F wasn't saturated enough,
especially in the yellows). 100F also produces more accurate colours.
I can't find a good comparison online apart from Ken Rockwell's.
