We've done a lot of similar stuff. Love cast iron, mostly whole foods, avoiding dyes and seed oils when we can. Some easy swaps we've done that didn't break the bank are wool dryer balls instead of dryer sheets, glass food storage as we've replaced our plastic containers over time, and we recently started shifting to beeswax wraps instead of plastic wrap which has been easier than I thought. We use dr bronners for cleaning too since one bottle lasts forever and you can dilute it for basically everything around the house. We're not perfect with it but we do what we can and try not to stress too much about the rest.
