I'd like to trade my cross bike, which is too big, for a road, but don't know which o

I also want a road bike that I can do some light touring on if I want (supported credit card type of tour). I've tried the Giant Avail, a Cannondale Synapse and Six-3, but what else would you recommend? Does it need the eyelets for the racks if I want to tour with it?

Only if you want to carry stuff for touring.

There are gizmos that can attach baskets and bags to your bike without rack brazons/eyelets....but you might not want to carry anything over 5 lbs that way.
It's possible you might enjoy touring and want to do more adventurous touring after a while- why not get a bike with the necessary brazons for racks to begin with? Hard to add those things later.
Another consideration for touring is your posture on the bike- would you be comfortable for 5 hours on the bike in a bent down racing position?
Also for touring consider a bike that can take wider/sturdier tires if you want- some road bikes cannot take tires over 25c wide.

It does sound like you bought the wrong bike for what you need. A cross bike will have much less standover, but they pretty much expect you to do flying dismounts & mounts

I'd suggest finding your local cyclocross community online and trying to sell it there first. Might get a better price than via the shop - it's mid season, may get lucky with someone wanting to replace their bike, or jump in and give it a go.

good luck!

regarding touring on a road bike. you do not need eyelets or other fixed hardware to afix racks for loaded touring. Old man mountain and axiom sell racks that mount through the quick release and caliper brake or canti brake mounts. I used these (OMM, front rack; axion, rear rack) to carry over 60 lbs of gear on my road bike for several weeks last summer.
