Will my Sora FD work with my 48/38/28 crankset?
Which Sora? FD-3503 is designed for 50-39-30, so it should handle 48-38-28 OK as long as moving it down 4mm doesn't get you into chainstay interference territory.
Which Deore? There must be a hundred Deore FDs, many designed for much smaller MTB rings, but some specifically designed for touring bikes with 48T big rings.
Which clamp size? A slightly short BB might work with a 28.6mm clamp because the whole FD alignment varies a bit between clamp sizes, so the skinny tube variant has more minus tolerance on the chain line than the fat tube versions.

Sora FD-3503, yes. Have cabled it up with that, will see if it works.
Deore one I'm not sure. Looks very similar to this:
My frame is old school steel, so I guess 28.6mm clamp diameter? Deore one is 34.8mm unfortunately.
Thank you for your response.

It doesn't shift too badly with the Sora FD-3503.
The only thing is that when I'm in the middle ring and anywhere from the fourth smallest cog to the smallest, and shift into the smallest ring, the chain will sometimes fall between the middle and the smallest ring.
This could easily be avoided by first shifting up the cassette before shifting into the smallest ring (which I should be doing anyway), but any idea what could be causing this?

I also have a Deore one, but the clamp diameter is too big.
Also: I've installed a 119mm wide bb instead of the stated 121mm.
Will I be able to get my FD to work, or is the crankset too much inboard now?
