@RzrbkFarmer58, welcome to the forum! and welcome to the cattle business as well.
You've started with the feds in getting a farm loan, but you went to the 'dark' side of the USDA, the FSA (just kidding). Convert to the "Rebellion" and now go to the good of the USDA and work with the NRCS on a grazing plan. (OK, enough Star Wars references). I'm a Grazing Specialist with the NRCS and write grazing plans all day long. (Well, not as many as I used to but now I train others).
In terms of rotational grazing, you will want a minimum of 5 separate paddocks to rotate your herd through, so keep that in mind for permanent fencing. Review the "Four Never Fail Rules of Grazing". You can read book after book after book about rotational grazing, but this "Half Page" list of rules will tell you 95% of what you need to know about grazing/pasture management you need to get started. It was designed to be exceedingly simple and easy to comprehend.
The stand of grass that you have there looks to be in good shape. Get a soil test and I would say a minimum of two soil tests, one for each side of the road. Take note of the pH and adjust this if it needs adjusted before you ever fertilize. The pH has an effect on what the soil test shows is in the soil. It also affects the availability of nutrients to the plant.
You asked about cow/calf vs stockers. That's very much an individual choice. You talked quite a bit more about the CC. If you want to focus on a specific breed/mix, find a producer that has those. If you are after quality animals, stay away from the sale barn. I'm not saying its bad, but it is 'pot luck' and you have to remember that all the problem animals get brought there to be 'disposed of'. Overall, raising stockers will most likely give you the biggest profit and the fastest return. Also understand that stockers are a 'bunch of rowdy teenagers' that can be harder to manage than a 'laid back' cow.
Starting out, I would create a herd that would be composed of a "3 way cross" for hybrid vigor if I was going cow/calf.
I'll add that if you are needing stock tanks, fencing, seeding, brush management, paid for rotational grazing, other practices, the NRCS awards contracts with cost share for these practices based off your grazing management plan.
