I've got a lead on two trailers.
My trucks hauling capacity is 9,400 lbs. So one trailer will haul less and the other more. As I see it, the heavier trailer will cost more in gas and wear and tear on the truck when using it for light weight stuff, but I don't want to miss out on hauling jobs because the trailer is too light.

I think you're going to miss out a lot more hauling jobs due to the short 16' trailers. Even a compact tractor with a brush hog is going to hang off the tail of a 16' trailer. An 18' would be minimum for me WITH brakes. And I think that after hauling your 9400# max on any trailer will satisfy your thinking that you need extra heavy duty - that's buying extra weight carrying capacity that you'll never need with your truck. There will probably never be a time that you'll want or need to haul that much weight on a 16' or 18' trailer.
My trailer? 20' PJ pulled with either my 1/2 ton Chevy or my 3/4 ton Chevy. Yeah, it's the "Chevy" part that is the limiting factor. Next p/u will be a 1/2 ton Ford EcoBoost for sure.
I'm not a fan of dove tail trailers, but that's just me. They do have some advantages, but some negatives as well.
Buying a trailer will have some compromises, but you're getting a lot of good advice on here from some absolute experts. Good luck on your purchase.
Very interesting info on the Ford turbos. As one who lust over an Ecoboost F150 and owner of a couple turbo'd engines I've become pretty comfortable with their benefits vs drawbacks, sort of figuring they're so common that Ford even being relatively new to them for the mass market in the USA would probably be fine, guess I'm wrong. One thing I would guess would help (true on any engine), run it hard on regular occasion. An engine with that much power would have a high tendency to be run well below it's capacity a lot of the time, which can lead to the problems you discuss. Regular short trips combined could be a killer.
Sorry also for being OT.
