Using a $PGDATA subdirectory in a mounted Volume allows you to run with 0700
and also retain this limitation you mention. I don't believe this
limitation is a limitation
of Docker - AFAIK Docker uses the permissions from the Host Directory for
the Mount.

In my experience we have been using (since 2014?)  a subdirectory of the
mounted Volume
and run a statement similar to this on startup of your container, before
starting postgres/initdb or the like

install -o postgres -g postgres -d -m 0700 "${PGDATA}"

There's enough people running Postgres in Docker containers in production
for almost a decade.
It does work!
