A raised garden bed won't prevent the rhizomes from travelling, unless the bed is permanently sealed where it contacts, or near contacts, the ground. Remember that plastic can crack, split, and deform, concrete can crack also.
If you know a plant is invasive and difficult to control at the best of times (unlike an invasive that can have seeds removed or similar), then have a long think about it. It's like playing catch with a live hand grenade; the safest way is not to play. Clumping bamboo is the only choice if your climate permits it.
For me, on choosing what to plant, I would first consider that benefits me (food, flower, aesthetic, biomass) and that can be endemic, native, or exotic. If nothing suits that has a value, I would then choose a diverse small planting in endemic species to and around your area (also consider recommendations from climate scientists if you area will get warmer/colder/wetter/drier and select some species suited to that change).
