Given you’re elderly Id suggest a handrail and retro style metal verandah rail . Personally I wouldn’t obstruct access with a gate , I would fence the yard creating greater personal safety for yourself as well . Add a good security light and camera system to further deter intruders. See if your local Lions Club can help you out.
