There is a lot of research in designing a hydraulic system. Hydraulic components are expensive. Working everything out in advance is a must!
The 2 most important considerations are the desired force, and the cylinder speed. Once that is determined, selection of components begins.
There are many considerations.
Pump volume at given RPM, combined with cylinder piston area, will determine the speed.
Pump pressure combined with cylinder piston area, will determine force.
So, a 3500 pound pump with a small bore cylinder will apply the desired force faster than a 2000 pound pump with a large bore cylinder, provided they are the same volume and driven at the same power. There are hydraulic calculators available online to sort all this out.
It gets complicated, all the factors involved, physical size, economics, convenience, safety...
As for the capacity of the tank, that is based on the difference in volume of the cylinder in the extended and retracted position, plus the dwell time the oil needs in the tank for heat dissipation, and some common sense depth of the pump suction to prevent air getting into the pump.
If I were going to attempt this, I would do a lot of online research, owner reviews, Youtube videos, product specs, etc.
Once I found a design I liked, I would go see one in person. Take a camera and a note pad, write down the make and model of each component. Even if you don't follow that design exactly, you will get a ball park idea what they did, let someone else work out the problems.
You may also find there will be little savings in buying the components. Unless you have a source, or some extra parts laying around, the manufacturers can get bulk pricing and pass the savings along.

Today's Featured Article - Restoration Story: Fordson Major - by Anthony West. George bought his Fordson Major from a an implement sale about 18 years ago for £200.00 (UK). There is no known history regarding its origins or what service it had done, but the following work was undertaken alone to bring it up to show standard. From the engine number, it was found that this Major was produced late 1946. It was almost complete but had various parts that would definitely need replacing.
