What will a first timer’s likeliest mistakes/regrets when putting up a chain link fence?

I’m getting prepared to start a DIY chain link fence project. Somewhere 1000+ liner feet in a large rectangle perimeter of my yard.

I’m on the market for 1 person post hole auger, and laser level. I would rather buy/resell the auger instead of rent so I can take my time.

I know how to measure well and work with my hands though don’t have any experience with this type of work.

Can you tell me anything that will help me avoid beginner mistakes and/or ideas to make this fence look like a pro did it?

4 or 5 foot black chain link fence on mostly level clay with top soil. Am still deciding on powder coat or vinyl …

Thanks in advance!
