I’ve had great luck with good quality, vintage, wood furniture on Facebook marketplace but I also no longer use facebook. I am a huge eBay fan lol. Thrift stores, vintage stores, etc. are an amazing place to find some unique stuff. I’ve gotten some great lamps, coffee table books, glassware/vases, framed wall art. A lot of vintage stuff is going to be built better and of course more unique because it’s older, wasn’t mass produced to the scale that things are today, and especially with the way many people probably though theirs away leaving fewer to find. The price points when thrifting are also great.
