Ok I think I have a really great idea to make some money.
Cottagecore is getting big but it's literally just a look and nothing else, right
Make a corner of your house/apartment into that cottagecore aesthetic. Get a bunch of B roll of like meadows and mountains and forests. Edit videos of a small girl baking or cross stitching in that corner, and pepper it with that b roll of cozy small towns and woods and pretend you live there. The 'girl' doesn't even need to be pretty because it's best to not even show her face (to appease self inserts).
Then when you get a following, buy a bunch of 'handmade' greeting cards made by slaves in Russia and sell them on your Etsy claiming you handmade them.

You could probably make a season's worth of content in one weekend. One issue though is you'd have to make new content every season - cottagecore looks like it rides hard with the different seasons.
