This thread may be of interest, I’ve been on the verge of getting round to it for an age myself.
I’ve been a Picard user but I’m not in love with it. Tried a few other FOSS tools but nothing stuck. Beets promises better automation once you’ve answered it’s questions. It did seem extremely curious though when I tried a scan. It was late and I cracked under interrogation and went to bed.
Edit Yeah, CUETools doesn’t often (ever) really deliver on that front
