Unfortunately, however, all the AMD boards I have can only render 8-bit color to an output file and none of them even pretend to render lossless. The Nvidia and Intel gpus can do 10-bit and Nvidia presets have "lossless" selections which yield high quality (but a far cry from lossless) output.
@Howard-Vigorita What 10-bit preset are you using with Nvidia that does not work with AMD or have an AMD equivalent?
I've never seen an amd preset for 10-bit anywhere. The driver has a 10-bit color depth setting but I think it only applies to the display... on my little navi it turns on 10-bit and 12-bit display options. But has no effect on render color depth. Not even with the amf ffmpeg libs. For accelerated 10-bit rendering, Nvidia and Intel hevc are pretty much the only games in town... all their hevc presets have the 10-bit option which is greyed out for amd presets.
This is not a particularly favorable time for many computer upgrades. But my 5-year-old i7 CPU is dragging relative to newer, less-expensive i5 ones, so I decided to do an incremental upgrade: I purchased a Z590 mobo (less-expensive MSI "Pro" type; not "Gamer" type nor super-overclocker type) and an intel Core i7-11700K.
I had been debating between a Ryzen 9 5900X and an i9-11900K. The former is only available at inflated prices, and the latter is getting absolutely savaged by online reviewers. But then I decided to check out one step lower on the CPU scale, since I was not going to upgrade other parts of my editing machine... and I feel confident that the 11700K will give me sought-after improvement in VEGAS Pro 18 responsiveness. It has the great advantage of being available and far less expensive than the other ones I thought I wanted. The main advantages of the i9 in this generation over the i7 are likely of marginal practical value for me, and the cost difference is more than I think is appropriate for my specific circumstance.
Fingers crossed...

Solid reasoning. You made a good decision. The 11900K is simply a better binned 11700K overclocked by Intel to an inch of it's life resulting in an insignificant performance increase for a lot more money.
