@sacredhart you can run an SLX front derailleur from road shifters (105 etc), but you have to run road derailleurs. The only current clutch rear mech is GRX (good luck finding one!).
I'm running 105 shifters and rear mech, SLX front mech and chainset/BB on a Genesis Vagabond frame, it all works very nicely, so your Surly should be fine if that's the way you want to go.
