Best plants for abandoned raised beds w weeds taking over?

There is an abandoned raised bed garden that has been taken over by weeds that from what I can tell are mainly mugwort. Not sure about soil quality after all this time so don’t want to plant anything edible but does anyone have a suggestion about what I could plant this late in the season that would be 1) aesthetically pleasing 2) easy to grow from seeds 3) could thrive/crowd out the weeds? Thank you! This is a full-sun situation.
