As you mentioned, I took a look at RISC-V by first visiting the Ubuntu Server download page at the link below:
https://ubuntu.com/download/risc-v
It seems like currently there are only seven boards compatible to the Ubuntu Server OS.

Have you checked Debian? On page https://wiki.debian.org/RISC-V, they claim they support few more board.

And outside of the OS, I also need a variety of apps such as Fulcrum, Sparrow Wallet, Mempool, Bitcoin Core, etc. to also be available in a downloadable RISC-V format which currently are not. In short, I think it is too early to consider a RISC-V motherboard as a viable option to run a Bitcoin Node on.

That's mostly true. Although Bitcoin Core has RISC-V support, check it's download page at https://bitcoincore.org/en/download/.
