got it working, using the hint present in: https://www.redhat.com/sysadmin/debug-rootless-podman-mounted-volumes adding flag U to volume mount. For the future reference, following resolves issue reported above for podman rootless on MacOS (however leads to different ones, but that would be investigated separately):
