No particular experience from me, I've not run RP on a club layout but I did run some back and forth as a test on a small exhibition layout once as a test. They were using an NCE powercab I believe.
What the club your thinking of joining uses, whether NCE or Digitrax or even another NMRA compliant DCC system matters not, you can plonk your RP equipped loco's down and control them as per normal using your HC (it has to be an NMRA compliant system - it's to do with the voltage levels on the track).
If you want to run your loco's in DCC mode using the clubs controllers then you can do that to, you just have to enable DCC mode in the LM and set it up.
There are a couple here who have run their RP stuff on club layouts quite a bit, one, who sadly no longer uses RP and no longer visits here used to use it on Free-mo setups (which are DigiTrax) without operational issue and another, member KPack, who has also done so (but from memory, probably faulty, never said what system the club used) without operational issue.
The only thing to be aware of is in DCC mode there is a few things that just don't work as well, for instance you can't consist using NCE.
The only other thing I can think of is you might need to explain RP to them if they've not heard about it before before you can put your loco's on the rails.
