Well head and pump construction

I have a well on a property I just bought. It's 140' deep, and the water level may be at around 70 or deeper.
Right now the well consists of a 6" casing, 1-1/4" black (ABS?) pipe, electrical wire going down to the pump. We have established that the pump runs on 120VAC and produces about 10 GPM.
That's the good news.
The bad news is that I know nothing about this pump, but for obvious reasons I don't want to replace something that's working.
How do I get this to work correctly? I need both the electrical controls as well as the physical design of the well seal and associated plumbing like a pressure tank, check valve, etc. I know the general principles but I've never really designed a well from almost scratch. Youtube videos are a dime a dozen and few agree on what's needed.

I have not measured the current draw, but that's a good idea.
It's 2 wire (plus ground).
Not sure if it needs to run at night; the plan is to pump to a ground level tank, then use a second pump to pressurize the house and provide irrigation. Although we will be doing gray water reuse for the vegetable garden as much as possible.
Is there a safety rope attached to your pump? Using a black polypropylene tubing is ok if you have the rope also. I’d almost want to pull the pump and do it right. The well seal will need a hose barb attached to its underside and a couple hose clamps to attach the poly and an eyelet to attach the safety rope. Nothing worse than trying to fish out a pump from the bottom your well. You also want to “shock” the well with either a couple of pool chlorine tablets or a 1/2 gallon of liquid Clorox and let it sit in there 24hrs. I’d then pump out the well onto the ground for a couple of hours. Some pics of the well head would be useful.
Most submersible pumps are 220V. Is there a motor control box in the system? There should be one. A pic if there is one would be helpful.
Also no well seal. It's literally a 6" steel pipe with black tubing and a power cord sticking out the top. The power cord ended just bare laying on the ground.
We thought the pump was 220 but it would safety out after a few seconds, so we tried it on 120, and it pumped 10-20 GPM for an hour with no problem.
When I get back this winter I will probably pull the pump and do it right.
Any diagrams on how to set up the well seal? And what kind of rope to use for the pump?
For the electrical, I am assuming a disconnect and a pressure switch near the well head?
