I am a firm believer in Really Right Stuff lever quick release clamps, which is part of why I recommended above that you go with a RRS L bracket now, since you mentioned you may want to change to a lever release clamp in the future. With you at this stage in your collection of Arca Swiss items, it is so easy to go with RRS for the L bracket, and stay with RRS or Wimberley for plates, and keep fully open the RRS lever release option. And in practice, the RRS lever clamps actually clamp on to most any plates you throw at it, but a few are not clamped as securely as they should be.
Also, RRS is starting to address the plate compatibility issue to include even more plates and brackets, with their most popular lever clamp style now rated to clamp most anything. See the following link, and look down to the part in red text:
It is not clear when or if this improvement will find its way to their other sizes and types of lever clamps, but my guess is that it will.
