I’d recommend a Canon EOS Rebel T5i, T6i or T7i. They’re great cameras for beginners packed with features. You can also get a Canon SL1 or SL2; the SL1 is a mini version of the T5i while the SL2 is a mini version of the T7i.
As for lenses, the 55-250mm IS STM is the way to go. Don’t get the original IS or IS II version, they’re not as good, and have slow focusing. The 75-300, while cheaper, won’t offer as much sharpness, and has slow autofocusing (and no Image Stabilization!). If you have a bigger budget, you can get a used Canon 70-200 f/4L on Amazon for under $500. That’s an L lens (the white ones with a red ring) for under $500! That’s probably the best value, considering a whole bunch of them go for over $1000. (Note this lens doesn’t have Image Stabilization, so the images may be blurrier if you have shaky hands, or you’re using a slow shutter speed.)
You may also want an editing software. I use Adobe Lightroom Classic CC for $10/month. I prefer to use this over the CC version because there are more ways to edit photos. You can also use Lightroom CC Mobile or Snapseed for free.
Here’s a picture of what I use: A Canon EOS 77D with a 55-250mm IS STM (ignore the microwave 😂)
Note: my camera has a battery grip, which is an extra attachment on the bottom that allows you to put more batteries in
Settings-wise, it all depends on the environment and your lens. I’d recommend checking out @JRRaviation’s spotting guide for that one!
