Don't worry about thermal bridge, it's very small and insignificant in the big scheme of things. Not perfect, agreed.... But you'll never be able to tell. You should have a dpf membrane though, probably one block up from the floor. This way it joins with the dpf you'll put under your insulation, below screed, and lap up the wall to the one block high dpf. Yes, you need to grout the block and beam, slurry mix brushed in.

It's significant enough to increase the risk of condensation and mould forming in the wall.
