It's been about 4 years since I tried WSL (really hoping to replace macOS as a unix workstation with a robust commercial software market) but my file access and socketed-app experience then was definitely anything but seamless.
Presumably if only 4 years ago that would still have been WSL2, but they have done a lot of improvements over the years. The audio and graphics WSLg stuff is pretty cool. Maybe worth giving it another try.
not sure about your requirements, but pretty happy over here that nowadays i can just mount sshfs within wsl and access this from windows explorer without any special hacks.
