Hi, if this is of any help, I bought a Fuji X-T 10 body recently and, taking the advice of a pal who has the XT Pro 2, decided to use legacy lenses with cheap (£15 or so) adapters rather than pay a fortune (straight away) for a Fuji lens until I am sure which one I want. In terms of 'nifty 50s' I have a Canon FDn 50mm f1.8 that I share with my A1 when I switch to film, a Minolta MD 50mm f1,7 and a Helios-44 58m f2 M42 - all give great results and I am as fond of the Canon as you are. They're all cheap enough and if you're cool shooting in manual (which I don't mind) you might find this is all you need.
