I appreciate the suggested links, but these don't really answer my question. This is in part because the referenced pages simply don't go into the pros and cons of each connection type, and also because they are written in the context of recent model Apple computers and operating systems, whereas I'm asking in reference to an older model running an older OS.

So what I'm really hoping for is some assistance from an experienced forum member familiar with the setup I described, given that Apple's official resources are not helpful at this point.
When the first generation of Apple Silicon Macs were introduced, we immediately fell in love with the M1's ability to rival – and even go faster and run cooler than - higher-end, more expensive machines. The launch of the M2 and M3 with their performance and power efficiency improvements made us as giddy as any geek unboxing a new gadget. However, our excitement and praise about Apple's latest innovation once again waned considerably when we discovered the base M3 model (meaning not M3 Pro or M3 Max) shares the same single external display limitation as the previous M1 and M2.
Say hello to the OWC USB-C Dual HDMI 4K Adapter. It’s the DisplayLink powered solution for expanding your M1, M2, M3, and M4 machine’s digital window for easier video editing, seeing more of your workflow simultaneously, or even creating eye-catching digital signage. For the ultimate in convenience, we gave this compact, bus-powered adapter a USB-C power pass-thru port so you can charge/power your laptop.2 Being the leading dock innovator for Macs, we know you love having ports freed up on your machine!
With its compact travel-friendly size and bus-powered convenience, you’ll always be ready to wow an audience or a team with your newfound multi-display capability. No longer will you have to choose between power and dual displays, or take up a second USB-C port to charge your laptop — this handy little adapter features a power pass-thru port. Simply plug in your laptop’s USB-C power adapter to keep the electrons flowing.2
