Of the two charge controllers you've picked, the cheap one is actually a far better choice for what you want to do.
You want to get a charge controller that lets you run the load through it, and is programmable with either a timer or an adjustable low voltage disconnect. That way you can set it up to run the pump when the sun is shining or when the battery has plenty of charge. The Renogy will only control the charging, so you could find yourself with a very flat battery if you don't add in something else to control discharging.
If you want a branded version of the cheap charge controller, check out this one (but it's basically the same thing).
If you want something with similar features but better quality and functionality you could try this EPsolar controller plus this PC cable and temp sensor.
If you build it well, it will be safe. :)
Just use fuses and / or breakers where appropriate.
If you live in a cold climate, insulate your battery box so it doesn't freeze.
Also, if you use AGM batteries, they are usually fine indoors. I wouldn't keep flooded batteries indoors though, they outgas too much for my comfort.
I always vent my indoor battery boxes to outside regardless of type though, just for extra safety.
Solar panels from Amazon are generally good, read the reviews though for each seller / item.
If they're still selling them, I can recommend the Newpowa brand as far as '12 volt' panels are concerned. Have two of those, and two HQST ones; the Newpowa branded ones outperform the others by a small bit. :)
Monocrystaline panels are more efficient space wise, more watts per sq. ft. Used most in mobile installs because they offer the best use of the limited space on say, a vehicle roof.
If you have enough space though, the Polycrystaline will be less expensive per watt on average.
What's your budget like, and how much power do you need total? I'm not sure how much you want to spend on the system, so for now I'll just recommend a 'middle of the road' unit.
If you need 500 watts or less total, I'd recommend one of EPsolar's Tracer 4215BN units:

You'll also need the remote to monitor / configure it:

You also should grab the battery temp sensor for it:
