could I get away with planting bamboo in the back of the bed here (as circled in pink) (this would be in front of my fence) and then planting other grasses/shrubs/flowers in front of it ? I don't know if there are issues with contention for resources/nutrients/space (especially given I'm going to bookend that run with a couple of trees 8-12ft trees)
In short yes, but I would recommend something solid as root containment all the way around them to prevent them from spreading. The clump forming motherfucking triffidy bastards are more difficult to get rid of than Covid 19 once established.
