I have hand issues as well and find hiking poles work better than a cane- you can use two outside, switch between sharp tips and crutch tips, the loops mean you don't have to grip them all the time and the cork handles are easier to hold, also they are much lighter than canes and extremely adjustable.
Mine are made by Leki.
Wheelchairs are not an all or nothing thing either- I use mine for airports, theme parks, stadiums, and museums, anywhere standing would be necessary or distances have to be covered quickly. They can save your energy for more important or enjoyable activities.
