Please see: all of 4e. Specifically its Asmodeus's fault and the fact that wizards wanted to standardize Tieflings into roughly one type for 4e.
It's got a little better in 5e (especially since most people ignore the hard rules and just make whatever they want), but few dnd games in the past decade have had good Tiefling variety. We got colours and horns and that's about it.
I'm assuming Cambions are like the half-fiends template? Tieflings to me were always like the 2nd or so many generations after deluded line of the tryst with the demonic, infernal, or evil deity? Would be kind of cool if tielflings could have wings, but if sorcerers get infernal/draconic bloodline they will get that eventually. Do have a quick question though when I researched up on Tieflings, aren't we supposed to be awarded powers for hitting 3rd level as one like the drow characters did or is that later. Could have sworn the 5E rulebook I skimmed said they get Hellish Rebuke or Asmodeous Tieflings and Smite or some such as a Zariel line.
