Just after the pandemic started I couldn't get my favorite bread at the local store plus they ran out of flour and yeast. I had some flour left over from previous baking and some old yeast (that turned out to be dead). So I started making bread too and then sourdough, then rye and now sourdough rye with sunflower seeds. I'm getting much better at dough handling and reading the dough. Really love the taste of the different breads. I don't use any fat, oil or sugar in my breads either and find them very tasteful. My wife likes the sourdough better than the store bought stuff and I haven't had any of the loaves go hard or loose their tenderness before they are gone. I think that it the reason some recipes call for fat or oil; to prolong the shelf life.
I now have 2 sourdough starters going; a white one that is 9 months old and a rye one that is only 3 weeks old and already smells and tastes great.
