Not really sure about the possibility of an all-in-one type solution to this problem. There may be one, but I suspect you may have to do with the Broker method given the specificity of what you're after.
If you're looking for a light-weight Data Broker display addon and don't mind Lua-based configuration you can use
cargoShip. All anchoring and positioning and sizing etc. is done in Lua, it just handles the updating of the data strings. Normally I don't suggest it but I noticed you worked with oUF in the past so it's probably not above your comfort level. Of course, it depends how willing you are to get your hands dirty for such a simple type of addon.
