Has anyone used a cordless Soldering Iron for soldering wires to track and hard wiring DCC decoders etc.?
I wouldn't think they're suitable for assembling white metal kits or larger jobs, but is that the case?
Also, is it better to get a gas powered or electric, and if electric rechargeable batteries or replaceable batteries?

If you can afford it I'd say go for a Weller temperature controlled "soldering station" I'm still using one that is over 40 years old and still doing all I want from white metal kits to track, as well as electronic work - PCBs etc
Generally I'd stick to a mains powered soldering station or mains soldering iron for wiring work. A temperature controlled iron is best for kit assembly etc.
It's easier to obtain and fit different size bits/tips for Antex and Weller etc. mains irons.
That said, I do have a Parkside rechargeable "pen" style iron from Lidl and that works pretty well, however the tip is a bit fat for getting between N gauge sleepers to add track feeds or carry out fine work fitting decoders etc. It comes with me to exhibitions in my tool box in case of emergencies :) I bought a second one for my son to carry around in his band gigging tools.

In the past I've had gas powered soldering pens and open-flame micro blowtorches but they all got put aside after little use.
