P2S and PA6-CF practice models?

Long time lurker, not brand new at printing (BL A1). However, bought a P2S and Sunlu PA6-CF, and want to print practice models BEFORE 2A. What’s your go-to models to test/eval settings and outcome (besides benchy)? Will use 300blkoutfde and long/hot drying. Future will be printing FTNs and DeAR, etc. TIA
