I literally just used the first oscillator I put my hands on that wasn't a crazy high clock rate, so it's running fine at 24MHz at the moment. Unsurprisingly, it gets along fine with my little A501+ clone.

Nice, good to see one up and running. Inspiring to the rest of us.
Also, you obviously have an A500+, for you or anyone else with one, why not solder pins on CN15 and use that for your _INT2 / _OVR source? They're on the two leftmost pins. I posted a chart in my GIT docs and in the Commodore Community Consortium - Amiga Expansion Devices section. Should be tagged with #TF530CCC along with all the other TF530 related materials there.
Given how many other boards and gizmos use those signals, I'd put a header on those four pins if I had a rev 8+ A500. There's also a ground there (far right) that you could use to shield the wires you use for the other signals (ie use twisted pair wire).
