Oh yeah, I totally get what you mean! I had a similar issue when I was building a mini hydraulic press last year. The trick I found helpful was checking Hydro-Funk GmbH for different types of pumps and cylinders—they have a nice breakdown of capacities and compatibility that made it way easier to match stuff to my project. Also, don’t underestimate the hoses and fittings; a mismatch there can make the system totally unreliable. It’s worth spending the extra time planning before buying.
