Well, thank you all for pointing me in some directions. I'll definately have a look at 'em later, I'm going to sleep pretty soon after I finish this post.
As I think about it, it seems likely in mind that some of the mods I had in mind might--unfortunately--no longer exists. Models that I tried out around 2000, back when I was a slightly-different person with a slightly-different taste. I tried all sorts of mods, from simple reskins of the F-CA stock model (that improved the look) to waaay oversized Starbases (with no hardpoints and break models) to some of Reign1701a's earlier sound and graphics mods (not exactly the ones you pointed to WZ, but thanks) where most were voices rather than LCARS noises (before SFC2 came out with voice sounds) and even had one particular TNG-esque firing sound (unique to TNG, no other series had it).
If I remember to check other websites I remember, I'd be pretty sure that there's a good chance that stuff from the War Refit Spacedock for SFC1 and 2 are still there, and that some other earlier mods--like those from Newships (which I have all ten or eleven packs of)--might exist after all. I kind of missed those mods, mods such as those early models of TNG ships (like a "Galaxy-class deluxe" model or an early EARLY Sovereign-class model or what not, from the SFB to SFC website).
Again, just thoughts of the past SFC days, back when modeler's talents back then paled in comparison to their talents today. I feel like I'm having a mid-life crisis too early in age... Anyhow, I'd like to thank everyone that pointed me to a direction. I might get a couple of lucky and not-so-lucky hits for what I wanted, but I'd at least have SFC1 mods.
