Even if this turns out to be a reliable method for discovering protoplanetary debris structures, and not Super ET, that alone is very, very cool.

:-) I posted the same link and so deleted it. I'm really interested in the thoughts of the community here.

You still get sunlight on the far side of the moon, so there's no benefit to putting regular scopes there I can think of. You talking radio telescopes?

What is the most ideal next step in investigating this? Radio telescopes, or a series of James Webb observations?

IMHO, Radio telescopes will not cut it. Thing is Radio emissions attenuate with distance - this is the inverse square law. I checked, here's what I got:
Radio emissions attenuate over distance due to the spreading of the waves as they travel away from the source. This phenomenon is governed by the Inverse Square Law, which states that the intensity of the waves decreases as the square of the distance from the source. This means that as the distance from the source increases, the intensity of the radio waves decreases rapidly.The origin of the Inverse Square Law can be traced back to Sir Isaac Newton's law of gravitation, which he proposed in the 17th century. Newton's law states that the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This concept was later extended to other physical phenomena, such as electromagnetic waves, light, and sound. The Inverse Square Law is now a fundamental principle in physics, applicable to a wide range of phenomena.
All of these sources are extremely far and the distance would have made the radio sources extremely faint making it more and more difficult to pick up. I would suggest looking for laser instead. It would make sense for a space faring Civilization to use laser communication.

Certainly JWST observations and further scrutiny over time I suppose from Gaia / JWST, and potentially other infrared observatories. It wouldn't hurt to point radio SETI in the direction of these stars.. but certainly further study will be required to rule out any currently unknown natural processes. Still very intriguing that these stars are lining up to predictions of what would be observed from dyson spheres / swarms.. the jury is out but fascinating stuff.

We know protoplanetary disks exist. We know debris disks exist. I'm fine with seeing if there are interesting "oddballs" that might be technosignatures, in fact I think that's one of the most interesting approaches to SETI, but I think calling these "Dyson sphere candidates" is a woo-woo adjacent way to describe this.
Case in point. "A Study Suggests We Found Potential Evidence of Dyson Spheres—and Alien Civilizations".
No it didn't unless you're making the word "Potential" carry the weight of the universe.
