You could travel around your city and go to nursing homes just to play for an hour whenever they will have you. Work up some sing-a-longs as well, they usually love that, it gives them something to do that they enjoy and they are so appreciative and it will help you in a lot of ways you never expected. Still, the classical gigs would be wonderful for all of you. There are numerous places a person can do this if you want to just do it and not be paid. Usually the local library will listen to you and if they like it you can often put little concerts together. Find others who might like to do it too and learn to accompany them or make programs each of you playing your own complimentary pieces. There are millions of ways to play if you want to do it simply for enjoyment. If you want to get paid it often gets a bit more difficult but there is no reason to expect that you cannot. If you find out that you like to accompany you can make some money doing that and that is a distinct skill that is very useful and always needed!
At 64 years old I have spent my life on stage in various groups large and small. It is in a small area mostly but I have done some bigger things. I am nearing the time when my skills are becoming difficult to maintain for playing in the orchestra and will likely have to retire soon. I cannot imagine not ever doing that again but I have had my time and it was a life well lived doing that.
I would encourage you to look into all of those ideas. They are all helpful to more than just yourself but will bring you much joy. Music is for sharing if you can do that. This makes me happy. I am going to take up smallpipes when I am done. Never stop, never.
