I bought a 2x16GB V-Color Manta XSky DDR5-6000 CL30 kit for $380 and plan to use it with a Ryzen 7 7800X3D. I was initially unsure whether moving to DDR5 was worthwhile, since some slower DDR4-based CPU options looked slightly more expensive despite being around 20% slower. Was this a reasonable purchase, or did I overpay badly?

The only real alternative would have been choosing a different platform that supports DDR4, but that would mean giving up the 7800X3D. For a new gaming build, pairing this CPU with DDR5-6000 CL30 is completely reasonable.
The specifications are an excellent fit for an AM5 system. DDR5-6000 with CL30 is generally considered a sweet spot for the 7800X3D, and current pricing for comparable kits can be over $400, so $380 is not a bad deal in the current market.
You made a sensible choice. Building an older AM4 or LGA1700 system from scratch just to save a little on DDR4 usually doesn't make much sense, especially if the alternative CPU is slower and costs more. The 7800X3D requires DDR5 anyway, so this is a strong memory choice for that platform.

That was what I was trying to figure out—whether choosing a roughly 20% slower DDR4-compatible CPU would have been worth it just to reduce memory costs. Sounds like sticking with AM5 was the better move.
