Good Advice there!
I have downsized several times. One small piece of advice that I have is to be prepared to upsize if the game doesn't meet your needs.

I have said that I'd like to grow everything we eat all within a few feet of our backsteps. Maybe yet, I will try to achieve that goal.
Sometimes I'm a little envious of a more
stable environment but to gain that here requires protective growing. Environmental stress limits square foot production and it's not just cold weather. Also, wind and intense sunlight - protection can also extend to protection from pests.
Early maturing usually means small size. Not necessarily small size of what you want for the table. And, with a stable environment, early maturity doesn't need to just be for the early season.
This year, bok choy starts were just too much to push into the outdoors beds so, some of them went into a greenhouse bed. It would not have surprised me in the least if they had just burned up. Not so! The greenhouse was built entirely with the idea of Winter and early Spring weather in mind. Ventilation is
very limited. That little bed has grown wonderful peppers through the Summer with the door and vent fully open through the day but it's HOT in there! Cool season bok choy? It worked! Late started, those plants are every bit as large and nice as those grown early, outdoors.
Succession planting - it's a very good idea. Experiment with early season crops. Sometimes, it feels like "getting away" with something. Like sowing pea seed in what is the usual week for the highest temperatures of the year. And, Good Luck with it all!
