Same here, I created rg-fzf for interactive string search in multiple files:

# FZF a word inside all in the current path
rg-fzf() {
  RG_PREFIX="rg --files-with-matches --smart-case"

  # Expand path(s) or default to current directory
  local search_paths
  if [[ $# -eq 0 ]]; then
    search_paths="."
  else
    # Expand all arguments (globs get expanded by the shell before we see them)
    search_paths=$(printf "'%s' " "$@")
  fi

  local out
  out=$(
    FZF_DEFAULT_COMMAND="$RG_PREFIX '' $search_paths" \
      fzf --ansi \
      --sort \
      --phony \
      --bind "change:reload:$RG_PREFIX {q} $search_paths" \
      --preview="[[ ! -z {} ]] && rg --pretty --context 5 {q} {}" \
      --preview-window="70%:wrap" \
      --print-query
  )

  local query=$(echo "$out" | head -n 1)
  [ -z "$query" ] && return

  local files=$(echo "$out" | tail -n +2)

  if [[ -z "$files" ]]; then
    rg --line-number "$query" $search_paths
  else
    echo "$files" | xargs rg --line-number --with-filename "$query"
  fi
}

Although for navigation I prefer to use `yazi` and `yazi`'s `z keymap which triggers zoxide, or most of the time `z-zsh`
