SPD clipless pedals with 9/16" shaft?

With all due respect, you've got it backwards.

SPD's _typically_ have a 9/16" thread.

What you need is a 1/2" thread. (and I've never seen one like that)

SPD's on an old Speedster? You is one sick puppy. On my current
three-speed project, I'm going to stick with rattrap pedals:

that "normal shoe" pedals make it a lot easier to hop onto the bike for
a short errand.

Very true. My city bike has rat traps with no toe clips, but if I were
to replace them, it would be with the lovely and affordable MKS
platforms & clips:

Hmmmm. Ok here's what I did.

I have the original pedals on there and used Park Tool's
Pedal wrench to them off, and used the side that had
9/16" marked on it. Not knowing any better, I tried to
install a set of Shimano M515s, and of course they don't
fit since the shaft is bigger. They fit on the side that of
the pedal wrench marked 15mm.

What did I miss in my foiled experiment?

I did more reading and 1/2" is indeed what I need.
I'll look into those adapters someone mentioned.
Thanks folks, as always!

Pedals with a 9/16" shaft have flats for a 15mm wrench
(unless they don't have flats). Pedals with a 1/2" shaft
have flats for a 9/16" wrench.

Wrench size vs. thread size. The 15mm wrench typically fits 9/16"
thread pedals. The 9/16" wrench typically fits 1/2" thread pedals. This
may not always be true, but it esplains your issues.

You're confusing the distance across the wrench flats with the pedal shaft
diameter.
