I have to say that I was really surprised that apparently there isn't a general solution for gluing together different-sized drives in an array reasonably-efficiently other than Synology's Hybrid RAID. I mean, you can build something that works similarly on a Linux machine, but there apparently isn't an out-of-the-box software package that does that. It seems like the kind of thing that'd be useful, but...shrugs
I think unRAID does that. But I never looked into it much tbh.
Both UnraidFS and mergerFS can merge drives of separate types and sizes into one array. They also allow removing / adding drives without disturbing the array. None of this is possible with traditional RAID (or at least not without a significant time sink for re-making the array), no matter the type of RAID you use.
