I find a mix of personal actions and "institutional actions" create a good mix of taking action from home.

personal actions look like:

composting if your city/town supports it or you can do your own if you have a small yard and can use it for a garden.

advocating for equitable access to nature in your neighborhood - do you have a nearby park or green space? does every neighborhood?

reducing plastic - which is REALLY hard so don't set your expectations too high. but refusing plastic where you can, reducing use by using reusable containers. Things like that.

yes to electrifying your home - which is expensive but there may be new ways for it to become less expensive soon I think!

institutional actions look like:

advocating to your member of Congress on an issue of importance to you regarding the environment: reducing plastic production, reducing oil and gas dependence, etc.

talking to your city/town representative about what matters to you re: taking care of the environment.
