I use an M6000 11s rear mech with a Saint 10s shifter & Sunrace 10s cassette and it works fine. Not sure if the ratios are 100% the same but close enough.
Thanks. I think rd-5120 is my guy. Officially up to 46t in 1x and 42 in 2x, both of which are cassettes I already have, and importantly cheaper than the SLX.
