Nice frame LPR. I would love to try a 753 frame just to see what all the fuss was about back then. They're probably not as good as modern high-end steel tubes but then again it would out-perform me any day!
Your brake lever choice is determined by the rest of the kit isn't it? I don't know when the frame was built but I'd probably go for aero levers, mainly because I prefer the smooth look (oooer missus
I don't know the Mafac ones you mention but I always associate Kronos with time trial bikes so they wouldn't get my vote. Looking at that headset you could be on for a Campag C Record build (£££ ouch) or something else of that era. The last run of Super Record gear might look good with white lever hoods and non-fluted cranks. A period correct Dura Ace or Suntour Superbe groupset would look good too of course. So many choices - I don't envy you.
As for pedals I'd go for the two pronged approach. Get some nice quill pedals with toe clips if they match the rest of the groupset just for 'photo purposes and put some clipless ones on when you ride it.
