How do I achieve a 'seasoned' style without making my room look dated?

I'm finally tackling my living room refresh, and I keep running into this concept of 'seasoned style.' I like the idea of something that feels lived-in, sophisticated, and timeless, but I'm terrified of going too far into 'rustic' or 'antique' territory and making it look like a museum. I'm looking for that perfect balance-the kind of style that suggests history and comfort without sacrificing modern clean lines. Does anyone have tips on mixing old-world elements, like distressed wood or vintage textiles, with modern furniture pieces? I want it to feel curated, not cluttered. Any advice on color palettes or material pairings would be hugely appreciated!
