It is, as you say, all about the offset.
Most aftermarket wheels of various sizes are listed as TR7 as presumably that's the dominant market for 95.25mm? As you say, very few are actually suitable and regardless of their size the cars can look comically under-wheeled.
The only 14s and 15s (I have the latter) made in the sort of offsets that suit are KN Minators. Visually similar (though much better made) to most generic Minilite replicas, these were marketed to Caterham owners and the kit car scene.
My 15s have 185/45s and feel compliant enough to me, though obviously this is subjective.
I'm not a fan of anything MGF-related as the wheels (made by Smiths, I think) are chronically heavy compared to others.
Stud conversions are okay if by means of a new hub, not massively keen on adapters. And it's cheating!
Good luck in your search. I've sold about 25 sets of 95.25 collection in the last year or so, with about 10 remaining. Brakes (and lack of power!) aren't so much of a consideration, so I've tended to towards period 13s in the 'to keep' pile.
