We are still battling on in spite of creeping decrepitude. I used to run 2 allotments and I actually found that easier than having a limitless veg garden here. Over the years we have compacted our growing area bit by bit, until we now have just two areas outside which we use in alternate years, and cover with poultry house cleanings and a tarp over the following year. I have whittled down what we grow in these flat beds to potatoes and broad beans, both staples of our diet. I used to grow brassicas of all sorts outside but slugs, high winds, heavy snow and pigeons have won (netting against pigeons works but then I don't weed them, which makes the slugs worse, and the net with snow on smashes down the plants). I grow a few brassicas, just enough, inside the polytunnel now. Onion family I used to grow outside, but although they grew well, they didn't store as they were too wet. They now take up too much space in the tunnel too - garlic, shallots, onions and leeks. Onions are a total waste of time as you can buy organic onions grown in a hotter country, which store well. All the other crops I grow inside: climbing beans, squashes, cucumbers (gherkins instead this year) , tomatoes, peppers, chillies, all salads, beetroot etc. The only crop I'm stuck on is peas. We love them, fresh from the plant, but so do the pigeons and mice outdoors, and spider mite and mice indoors. So this year I'm not growing them, but wish I was. Same with sweetcorn - it won't grow outside, but spider mite and mice, plus sparrows get them inside, so those are off the list forever. As well as the flat beds outside, we have a couple of raised beds, one for strawberries, the other for French beans, carrots, beetroot or parsnips, whichever I go for each year. I can keep those weeded except in a wet year. Herbs I grow near the house in an old dairy water bath so vermin and small male dogs can't get at them. I have tried herbs in pots but daren't eat them for what might have landed on them!
So the answer to some extent is to cut down on how much you grow, so you have enough for most meals, but no glut, and nothing which gets blootered each year. I have also become very stingey and don't give any veg away, except rhubarb as we have mountains of it. Most other folk we know are younger and fitter than me, so if they want veg they can grow their own!
