I also can't get tab completion in bash without specifying the sub directory
with neither app-shells/bash-completion nor pass's built in bash completion.

For me the best alternative is to use fzf and a custom fuzzy completion [1].
This example uses code from pass's zsh completion helper [2].

_fzf_complete_pass() {
  _fzf_complete +m -- "$@" < <(
    local prefix
    prefix="${PASSWORD_STORE_DIR:-$HOME/.password-store}"
    command find -L "$prefix" \
      -name "*.gpg" -type f | \
      sed -e "s#${prefix}/\{0,1\}##" -e 's#\.gpg##' -e 's#\\#\\\\#' | sort
  )
}

`pass **<TAB>` to trigger the completion, search and Ctrl+J/K to select the entry.
Setting up a dedicated completion key [3] makes the flow a little faster.

Just saw that this same discussion happened a few years ago too [4].
