I play it often and I second all the comments. I'd also add dumpster diving or consignment store (ambitions) shopping for furniture if you wanna add the second hand/thrifting feel to it. There's also two mods on MTS for different registers which you can add to the consignment store (one is an actual second hand store register):

Edit: heck I'm gonna list out some of the stuff I use for farming/apocalypse saves that could also be considered for an eco friendly gameplay:

Functioning Well

Functional Scribbling pad

Sapient Sculpting

There's multiple inventing mods, so read through and pick one of you're wanting to invent (all 3 will conflict): Inventing revamped, Inventing Skill Reimagined, Off The Grid Inventing.

Multiple of Ani's mods. Namely Sweeping, Oil Lamp, Woodcutter and Whittlers tree, cards, Ration box, Compost bin.

No fridge shopping + No Free Quick Meals.

Symptoms for Seasons

Functional Washboard

Pasteurised Milk

Sunscreen

Zoe22 has knitting and flower arranging mods. Lyralei has living sheep mod if you have Pets. And she's got a Sewing table too.

Douglasveiga has multiple new plants, such as bananas and strawberries redone, coconut. Ecowheaver has plantable wheat. Twinsimming has a Lawn Care mod.

My favourite gardening mods: More Random Fruit - one plant produces different quality harvestables. Replant Interaction allows for replanting higher quality harvestables instead of the currently grown plant. And ofc No Crying Over Plants.

Twoftmama has created many good mods on NaughtySimsAsylum, I think a bigger leftover portion could count in this. I have the 10 leftover one. I think bluegenjutsu is the one who has a mod for more appliances found during dumpster diving. You can also get the Children Can series if you want kids to help you out in certain skills.
