There shouldn't be any technical difficulties above your reach in BWV 1052, but I think you'd be expected to deliver way above technical level and into grasp of style, nuances, etc. if you play this.
I'm sorry to give the same ole boring suggestion: pick one of Mozart's. Easiest first movement would be that of no. 19, K. 459. If you want more technical challenge, try no. 21 (K. 467).
